Boyfriend Kissed Another Girl

42 replies

NewUser2025 · 06/10/2025 13:50

My boyfriend (M27) and I (F26) have been together for four years. He was loving, patient, and kind - someone I trusted deeply. This was my first real relationship where I felt I could be fully myself. He’d always been sweet, loving, generous and supportive.

When we met, I’d just started university with long-term plans to immigrate. I was clear about this from the beginning. Despite his hesitations, mainly due to his aging father’s declining health (Diabetes), he pursued me and said he’d come with me when the time came.

In July, his behavior shifted. For the first time, he became distant, distracted, and emotionally withdrawn. I initially blamed work stress and our ongoing talks about the future, but two weeks ago, I noticed he was acting secretive about his phone. Out of suspicion, I checked his old, synced phone and found weeks of messages with a 21-year-old former colleague, Louise (his boss’s younger sister). Their chats weren’t flirty, but emotionally intimate. They bonded over shared musical and political interests, talked about university experiences, and exchanged personal stories and miscellaneous photos. It felt more emotionally loaded than just casual conversation.

When I confronted him, he claimed it was nothing… until I threatened to call her. She later told me the truth - they kissed twice during a work night out. The first was spontaneous and after a regretful talk outside, they kissed again.

He later met up with her to apologize and cut things off, saying he felt confused and scared about his future with me, especially with me possibly moving abroad. He told me they spoke for a couple of hours, and when he tried to make her leave his car, she was unwilling and tried to hug him, saying it was “cruel” of him for not reciprocating.

He’s since reflected, told close friends, and insists it was a moment of self-sabotage driven by insecurity and not a desire to be with her. He says it could’ve been anyone, and that it wasn’t about her specifically.

For the past two weeks, we’ve had difficult, honest conversations while sleeping separately. We’ve spoken vulnerably about the ways we’ve drifted, his emotional state, his fears of abandonment, and how he’s struggled to open up to me, feel good enough for me or live up to expectations I never had of him to begin with.

He says he didn’t want to seem weak, and that he didn’t know how to express that he was feeling lost. He’s expressed deep regret, wants to try again, and is willing to go to therapy (individual or couples). He’s been emotional and says he doesn’t want to lose me if I think there could be a way to rebuild trust.

I’m heartbroken and unsure what to do. This is my first time going through something like this, and I feel completely lost. Can I ask you please be firm but kind. I genuinely never expected this of him, of all people. It’s an actual punch to the gut. Thank you.

Chuck him in the bin op.

Life is too short, you have way to much living to do!

Dump

Channellingsophistication · 06/10/2025 15:30

It sounds like the relationship has run its course. You were very young when you got together and may be now you want different things.

I wonder if he wants to break away but feels bad about it. However, you have said he is wanting to try again. But he has kissed someone else though more than once....

You mentioned therapy but that seems a bit odd at your young age when you are not married and have not been together all that long. Perhaps if you dont want to end things some time apart might help you both work out what you want.

Reachedthefinalstage · 06/10/2025 17:35

It sounds as though he is not ready to fully commit to your relationship.

Namechangetheyarewatching · 06/10/2025 17:39

He cheated for a reason, known only to himself and he will probably do it again

You have outgrown each other, make him an ex and find someone who adores you

Odiebay · 06/10/2025 17:49

It might not feel like it but you have been given the gift of sight whilst he is still just your boyfriend.

The relationship will never be the same and the trust is gone. Go on your travels and leave him behind. Don't make the mistake of staying with him and signing up to this being your life every couple of months/years. You are so young!

Tubestrike · 06/10/2025 17:54

People tend to admit to the bare minimum when they've cheated, I'd dump him .

Endofyear · 06/10/2025 20:32

Sorry OP but it sounds like your conversations are all about him and his feelings - he's making a lot of excuses but his actions speak louder than words. He's cheated on you, lied to you and been messaging this woman behind your back. His behaviour, whatever excuses he's making now, has been deplorable.

If you stay with him and decide to give him another chance, I fear you will have more heartbreak down the line. You'll certainly have years of not trusting him and wondering what he's up to every time he's in an off mood or out late. Don't put yourself through it. You deserve better.

I’m genuinely scared that the next relationship I get into (if I do), that this will happen again. I really thought he was one of the rare few that wouldn’t give in to anything like this. I’m so devastated and wake up with a sinking feeling every morning.

ForTipsyFinch · 07/10/2025 11:44

People show how they feel about us by their actions. And his action of doing that is how he really feels... I would expect someone who does that once to do so (and more) again tbh.

CrostaDiPizza · 07/10/2025 11:51

The relationship has run its course, and instead of dumping you, he's hanging on to you. Cut your losses and move on.

Why do you think he would want to hang on to me given what he’s done? It doesn’t make sense if that’s what he’s doing, it’s so confusing.

Home comforts.
Like hanging on to a trusty old car even though he's looking for a new sportscar.

I’d be absolutely gutted if that’s what he genuinely thought of me.

Well @NewUser2025 , you're gutted anyway.

Blappengrap · 07/10/2025 12:34

Split up, have a break. If he's the right person for you then you'll get together later on, wiser and older. He sounds like he needs to grow up a bit and he can do that without you being around.

LavenderBlue19 · 07/10/2025 12:40

Nah, bin. You're so young, don't hitch yourself to someone you're not sure about.

The reality is you might get cheated on again. We all might. It's very common. But you might not, and it'll be a different life. Given that this one has already cheated on you, if he gets away with it it's highly likely to happen again.

It is easier to hang on to exes. I've done it myself (not cheating related, just someone I used to argue with a lot but kept going back to). Sometimes it works out in the end, but I think you both need to change and grow up a lot before you can get back together. Just staying together when the relationship has already been rocky, when there are no kids, no marriage - what's the point. Move on and enjoy being single for a while.

FrauPaige · 07/10/2025 12:44

You plan to emigrate and start a new chapter in your life. With a partner who is not on the exact same career trajectory, this would be challenging and would test the relationship.

However, with a partner that is clearly not committed and is showing that he wants to be able to explore relationships with other women, this would be both a distraction for your life and career goals, and a stress flash point for the relationship.

You are young, with so much ahead of you. You are not the same person you were when you began dating this man. Focus on yourself and continue to look forwards. This man will only drag you down and derail your career, and damage self-esteem, and mental health.

OchreRaven · 07/10/2025 12:46

It sounds like he doesn’t want the same things as you. He doesn’t want to emigrate. Whether he self sabotaged or gave into temptation the outcome is the same. You would both have to invest a lot to rebuild the trust. If he had come to you straight away and told you he had made a mistake at least you would know he wouldn’t lie to you, but you only know the truth because she told you.

I would be making plans on my own. Take time to settle in to wherever you end up and if after space you decide that your relationship really was all you had built it up to be, and you are in the place to try again, there are ways for it to happen. If you really are that special to him he won’t be able to get over you in 6-12 months. Give yourself time to understand how you really feel and what you want out of a partner.

bluevelvetears · 07/10/2025 12:51

He's pulling the sympathy card to excuse his behaviour. Bad sign. I think you would save yourself a lot of heartache if you ended but having been there myself I know it's not that easy.

I’m trying to make sense of everything.

MightyGoldBear · 07/10/2025 13:33

Op when you feel scared do you then kiss another person? In what world does that make sense. It's the biggest excuse and poor accountability.
He is deeply immature and not ready for a relationship, worse he is happy to stop you living your life. He is holding you back. That's not love.

Therapy for you alone would be wonderful. You need to learn yourself so this doesnt keep repeating. Why are you wasting time on him? He doesn't cherish you. Why don't you think you deserve more than this? Future you will thank you for following your dreams and your goals. Those that love us want that for us not to hold us back. The right people will be right there with you. Everything has become about him. Take back your power and start prioritising yourself. He wasn't thinking of you when he kissed her not once but twice.

I know it hurts. I'm so sorry is there anyone you can lean on for support? Friends family?
