I’m The Other Person in Someone’s Relationship — WTF Should I Do?

The Confession

A counseling request recently came in from someone who was carrying a secret they did not know how to talk about:

“I’m the other person in someone’s relationship. I didn’t mean for it to become this. At first, it felt like a connection. Then it became texting, feelings, promises, and waiting. They keep telling me their relationship is basically over, but they still go home to someone else. I feel guilty. I feel hopeful. I feel stupid for hoping. And I don’t know how much longer I can keep doing this.”

I am not going to share any identifying details about that inquiry, because it is not mine to share. But the feeling inside it is something couples therapists hear more often than people realize. Not always in those exact words, and not always with the same circumstances, but with the same emotional knot: I care about someone who is not fully available, and I do not know what that makes me.

If you are reading this because some version of that applies to you, I want you to know two things right away: this article is not here to shame you, and it is not here to help you stay stuck. It is here to help you slow down, look honestly at what is happening, and ask the harder question underneath the situation:

“Am I being offered a real relationship, or am I being asked to live inside someone else’s unfinished one?”

Being the other person in someone’s relationship can create a strange mix of emotions: guilt, hope, attachment, jealousy, tenderness, anger, shame, and the painful belief that if you can just wait a little longer, everything might finally become clear. But waiting can become its own kind of relationship — one where you are emotionally invested, privately available, and publicly invisible.

This post is part of our WTF Should I Do? relationship series, where we look at complicated relationship situations people often feel embarrassed, conflicted, or unsure how to talk about. Let’s talk through this one honestly.

Being “The Other Person” Is Usually More Complicated Than People Admit

Nobody plans this. Almost no one wakes up one day and decides, “I’m going to fall for someone who’s already committed to another person.” It tends to happen sideways — through friendship, through vulnerability, through late-night texting that started as something else, through a closeness at work that felt harmless right up until it didn’t.

Somewhere in there, the feelings became real. Maybe you told yourself it was just chemistry, or just talking, or just a thing that would run its course. And now you’re in a situation where you feel both chosen and hidden at the same time. You feel special to this person — and also aware, on some level, that you’re not fully theirs to claim, and they’re not fully yours.

That combination is disorienting. You’re receiving real intimacy — attention, affection, maybe physical closeness — without the public acknowledgment or the real-world commitment that usually comes with it. That gap between how close it feels and how little of it can be said out loud is part of what makes this so hard to sit with.

Before You Ask What They Should Do, Ask What You Are Being Offered

It’s tempting to spend your energy analyzing their marriage or their relationship — whether it’s really over, whether they’re really unhappy, whether they really mean it when they say things will change. But there’s a more useful question, and it’s about you: what are you actually being offered right now, today, not hypothetically?

“I’m the other person in someone’s relationship.”

There’s a real difference between words and actions. Between a promise and a plan. Between “I’m going to leave” and any observable step toward leaving. Between emotional intensity — the kind that feels like the deepest connection you’ve ever had — and relational availability, which is a much more boring, much more necessary thing. And there’s a difference between being desired in private and being chosen openly, in front of other people, with your name attached to it.

WTF Reflection: Are you being offered a real relationship, or are you being offered emotional access to someone who is not actually available?

Those two things can feel identical from the inside. They are not the same, and the difference matters more than almost anything else in this situation.

The Waiting Room Can Become Its Own Relationship

One of the quieter costs of this kind of involvement is how much of your life can start to orbit around waiting. Waiting for them to leave. Waiting for them to decide. Waiting for their partner to find out, or not find out. Waiting for the relationship between the two of you to become something you can actually talk about with your friends.

While you’re waiting, your own life tends to get smaller. Plans get built around their availability. Holidays get spent alone or with a version of the story you’re not sharing with your family. Friendships can quietly erode because you can’t be fully honest about where your time and attention are going. You may notice you’ve stopped dating anyone else, stopped putting energy into your own goals, stopped doing the things that used to make you feel like yourself — because so much of you is tied up in a situation that isn’t fully yours to shape.

A waiting room isn’t a relationship. It’s a holding pattern. And holding patterns can last for a very long time if nobody names them.

Secrecy Has an Emotional Cost

Even when the connection itself feels good, the secrecy around it rarely does. Hiding a relationship — or a situation that functions like one — tends to come with a specific kind of low-grade anxiety. You may find yourself hypervigilant around texts and calls, tracking when they’re reachable and when they’re not, reading meaning into response times that probably don’t deserve that much weight.

You may notice jealousy toward their partner that feels uncomfortable and hard to admit, even to yourself. You can’t call them freely. You can’t show up in the parts of their life that matter — holidays, family events, the ordinary weekend stuff that most couples take for granted. It can start to feel like a relationship exists fully in your emotional experience, but has almost no footprint in your actual, visible life. That mismatch is exhausting, and it’s worth naming instead of just pushing through.

Mixed Feelings Are Normal — They’re Not Proof That This Is Healthy

If you’re feeling love, guilt, hope, shame, anger, fear, attachment, competitiveness, loneliness, and confusion — sometimes all in the same afternoon — that doesn’t mean something is wrong with you. It means you’re a person in a genuinely conflicted situation. Most people who end up here feel some version of all of that.

But I want to be direct about something: the presence of strong, mixed feelings is not evidence that a situation is healthy or sustainable. Intense feelings can show up in all kinds of situations, including ones that are genuinely bad for you. Feeling a lot doesn’t automatically mean you’re on the right path. It just means you’re paying attention to something that matters to you.

You May Be Hearing One Side of the Story

I want to say this carefully, because it matters a lot for how you think about all of this: you may only be hearing one side of their relationship, and that side may be emotionally convincing. It’s still one side.

Therapist Note: When someone describes their relationship while they are also pursuing you, you may be hearing a version of the story shaped by longing, guilt, frustration, or justification.

That doesn’t necessarily mean they’re lying to you. People in unhappy relationships often describe them accurately from where they’re standing. But someone who is emotionally or romantically involved with you also has an incentive — conscious or not — to frame their existing relationship in a way that makes their choices feel more justifiable. It’s worth holding that awareness lightly rather than treating their account as the full, objective picture of a relationship you’re not actually inside of.

Questions Worth Asking Yourself

None of these questions have a “correct” answer that applies to everyone. But sitting with them honestly, on paper if you can, tends to clarify things faster than turning them over in your head at 1 a.m.

  • What am I hoping will happen?
  • What evidence do I actually have that this person is available — not what they’ve said, but what they’ve done?
  • What am I being asked to tolerate right now?
  • What parts of myself am I quieting down in order to stay in this?
  • Would I want a future relationship that began this way — with hiding, waiting, and secrecy at its foundation?
  • Am I confusing emotional intensity with emotional safety?
  • What would I tell a close friend if they described my exact situation to me?

That last one tends to be the most useful. Most people are far more honest and far less generous when they imagine giving advice to a friend than when they’re inside their own situation.

What If They Say They’re Unhappy in Their Relationship?

They might be. Genuinely unhappy relationships exist, and it’s entirely possible theirs is one of them. But unhappiness in an existing relationship does not automatically translate into availability for a new one. Those are two separate things, and it’s easy to let the first one stand in for the second.

If someone is unhappy, what they generally need is to deal with that directly — through honest conversation with their partner, through individual or couples therapy, through a real decision about whether to stay or go. What they don’t need is to outsource that unhappiness into a hidden connection with someone else, because that tends to relieve just enough pressure to make the actual problem easier to avoid indefinitely.

What If They Really Are Going to Leave?

Some people do leave. It happens. I’m not going to tell you it never does, because that wouldn’t be honest, and this isn’t the place for tidy absolutes. But the real question isn’t whether leaving is theoretically possible. It’s whether this specific person is taking concrete, observable, uncomfortable steps toward it.

A real transition out of a committed relationship usually involves things that are hard to fake or hide: difficult conversations with their partner, logistical changes, financial and living arrangements being sorted out, consequences they’re actually facing rather than avoiding. If everything about the situation is still happening in private, with no visible movement in their actual life, that’s information — even if it’s not the information you’re hoping for.

A Boundary That Protects Your Dignity

You’re allowed to set a boundary here, even if it feels frightening or like it might end something that matters to you. A boundary isn’t a punishment. It’s a way of protecting your own sense of self while this situation gets sorted out, one way or another.

Possible Boundary: “I care about you, but I cannot keep participating in a relationship that requires secrecy. If you become fully available, we can talk honestly about what comes next. Until then, I need to step back.”

You don’t have to deliver that perfectly, and you don’t have to have it all figured out before you say some version of it. What matters is that it’s honest, and that it puts the responsibility for changing the situation where it actually belongs — with them, not with your ability to keep tolerating an unclear situation indefinitely.

When Therapy Can Help

Individual therapy can be genuinely useful here, and not just as a place to vent. It can help you understand your own attachment patterns — why certain dynamics feel familiar or magnetic even when they’re not good for you. It can help you get clearer on your values, work through the guilt or shame you might be carrying, and figure out whether this is part of a pattern of being drawn toward people who aren’t fully available. It can also help you build the kind of boundary described above and actually hold it, rather than setting it once and abandoning it the next time they reach out.

If the person you’re involved with is genuinely trying to decide whether to stay in or leave their relationship, that work belongs in couples therapy with their actual partner, or in discernment counseling if they’re trying to figure out which direction to go. Therapy isn’t a tool for making an outside relationship feel more legitimate, and it’s worth being honest with yourself about the difference.

This article is part of our WTF Should I Do? series, where we look at relationship situations people often feel embarrassed, conflicted, or unsure how to talk about. Being the other person in someone’s relationship can bring up secrecy, hope, guilt, attachment, and confusion all at once. The goal here is not to shame you. It is to help you slow down, tell yourself the truth, and think carefully about what this situation is asking of you.

Final Thoughts: You Are More Than This Situation

You are not beyond help, and you are not just “the other person” — that’s a role you’ve been playing inside someone else’s story, not the whole of who you are. But compassion for yourself doesn’t mean looking away from what this situation is actually costing you: your time, your peace of mind, your ability to be fully honest with the people who love you, and possibly your shot at the kind of relationship you actually want.

The next right step probably isn’t dramatic. It’s usually smaller and quieter than that — telling yourself the truth about what’s really happening, and letting that truth guide what you do next.
