AIBU? I kissed someone else after 6.5 years and a child

I'm going to write this as objectively as possible to get the most helpful responses.

The father of my child and I have been together for nearly seven years. Since having our child, our relationship has been turbulent, reaching its worst point around September/October last year. For a long time, we’ve gone through cycles - some days (or weeks) we barely speak, walking around like strangers, and other days, we’re madly in love. Very unsustainable, I know. It wasn't always like this, trust me. I love this man to death.

However, by last fall, I had reached my limit. I was overwhelmed - juggling work overtime, long daily commutes with our son (who is a toddler may I add), very little sleep, and constant relationship issues. I didn’t feel the environment was healthy for any of us, so I ended things. The breakup wasn’t calm or amicable, it was messy.

At the same time, he was dealing with a serious health crisis, including severe skin issues. He later told me it was so bad he legitimately thought he was going to die. He was hospitalized during this period. None of this really registered at the time and I did not check in on him. From my perspective, I was in survival mode - mentally and emotionally drained, trying to figure out my life after our family fell apart.

About two months after the breakup, while we were still living together (but not speaking), I kissed a coworker. It wasn’t a drunken mistake - it happened during a conversation about childhood trauma, and for the first time in a long time, I felt seen. It was one kiss, and we both quickly realized that pursuing anything further wasn’t right - not just because of bad timing but because we genuinely aren't a good match. He's a lovely guy and we are friendly around each other, nothing more. He has been seeing women since then so I know he's not into me, I don't get that vibe at all at least.

My ex found out and was devastated. I understand why - if the roles were reversed, I’d be heartbroken too. But I was honestly shocked at his reaction because, from the way he had verbalised himself in arguments, I believed he wanted nothing to do with me. Apparently, he also did not see it as a real break-up as it was similar in nature to the many we've had in the past. I personally disagree with this as we literally did not speak and barely looked at each other for so many weeks.

Eventually, we decided to give our relationship another chance, but he can’t move past this:
1. How I could do so only two months after our six-and-a-half-year relationship ended with kids involved
2. That I abandoned him during the worst period of his life when, in his words, even strangers would have done more for him than I did
3. That no man would be okay with the mother of their child doing this, and his perception of me has changed completely

Important side note: During our reconciliation, my coworker sent me two completely benign DMs over the Christmas holidays. Before getting back with my ex, we used to text, so this wasn’t unusual. The messages were along the lines of "Hope you have a great time in [destination]" (he knew I was traveling home) and "Happy New Year!" I didn’t respond and deleted them - not because I had anything to hide, but because I didn’t want my partner to see his name and assume there was something more going on as I knew it was a sensitive topic. At the time, I was just so happy to be back with my ex and fully focused on our relationship and didn't want anything to mess it up. Later, I told him about the messages, thinking nothing of it. In hindsight, deleting them was a massive fuck-up - it made it look like I was hiding something. Now, he says he can never trust me again because of this. I deeply regret it because if I had just left the messages alone, he would have seen how insignificant they really were. You're just gonna have to trust me on this one.

Overall, from my perspective, I definitely understand his pain, but at the same time, I truly felt abandoned myself during the breakup. I believed he didn’t care about me, so I emotionally detached to protect myself and my son, something I'm quite an an expert at due to childhood trauma. Now, I feel like he’s only considering his own pain and not mine, which doesn’t seem fair. But maybe I'm wrong.

So, genuiely so so so curious.... AIBU??

YABU – You should have been more understanding of his situation, especially considering his health crisis! Even if the breakup was necessary, not checking in on him and kissing someone else 2 months afterward is unforgivable. It may have felt like survival mode for you, but this is betrayal.
YANBU – I understand where he’s coming from, but you were also struggling and felt emotionally detached from the relationship long before the breakup. You didn’t intentionally set out to hurt him, and at the time, you truly believed he wanted nothing to do with you. Healing from a toxic cycle isn’t linear, and feeling seen after years of emotional distance is understandable.

This isn’t going to work. You weren’t together so you’ve done nothing wrong. It all sounds toxic and your best off out of it.

BillyBoe46 · 28/03/2025 20:48

Your biggest error was getting back with him. Your relationship doesn't work.

Ultimately, with the coworker you were separated and no longer in a relationship. You were free, single and able to do as you please. You didn't cheat and its none of his business.

With his sickness, well its nice to care about the person you coparent with wellbeing but again you were separated. He wasn't your partner or your responsibility.

To be frank, it sounds like he's using these things as a stick to beat you with, you were separated and actually aren't guilty of anything. Stop allowing him to are you feel guilty and acting like you cheated on him. You didn't.

This relationship isn't healthy and it's not going to last. The question is.... How long are you going to tolerate him and his bullshit?

Bruisername · 28/03/2025 20:57

You separated with him while he was in the middle of his health crisis and you hadn’t really noticed it?and you were still living together while separated?

the kiss is irrelevant here. Your relationship isn’t working. It doesn’t sound like you act as a team and that even before the separation you were leading quite separate lives

cheddercherry · 28/03/2025 20:58

You were separated so didn’t do anything wrong per se, but this relationship is toxic and not fair on your young child who has to go through weeks of their parents apparently not looking at or talking to each other. It’s not normal for him to be in the middle of you both flip flopping on whether or not you can tolerate each other that day. It plainly doesn’t work for any of you but it’s your son I feel for in all this.

I did notice, it had been going on for months but the state of it peaked during a really bad period between us. Argument was so bad I assumed he did not want to hear from me based on what was said.

Thanks to everyone for commenting

BakelikeBertha · 28/03/2025 21:04

He's feeling sorry for himself OP, and it makes him feel better to make you feel like shit! What does that tell you about him?

To me, it explains why the relationship wasn't working in the first place. It's now doomed, and for your child's sake, the sooner you end it for good, the better things will be.

1900s · 28/03/2025 21:09

Its all a bit off a mess really.
I think its best to go your own ways now and keep the peace for your childs sake.

TenderChicken · 28/03/2025 21:12

You both sound emotionally immature. Just end it for good, and focus on yourself and your child.

Fancycheese · 28/03/2025 21:14

It’s a mess. With kindness, because this all sounds awful, you need to get out of this relationship and into therapy. ASAP.

ItGhoul · 28/03/2025 21:27

You had been separated from this man for two months. You were entitled to kiss whoever the hell you wanted.

It is insane that you are repeatedly giving this relationship 'another chance'. It's incredibly toxic and dysfunctional and it is never going to work. You both sound addicted to the drama and you need to grow up.

How did your partner / ex-partner / whatever actually find out that you had a snog with a co-worker while separated, anyway? Did he read messages? Or did you tell him?

His health issues are entirely irrelevant to any of this. There's not some kind of rule that says you're only allowed to dump someone once they've passed a full health check ffs.

Sifflet · 28/03/2025 21:46

I think you’re focused on the wrong thing. This relationship isn’t working. Kiss or no kiss.

It’s definitely a mess! More than anything, I’m curious to hear unbiased opinions on everything that’s happened since it keeps getting brought up over and over again. I was also wondering if I might be seeing things the wrong way.

It’s really sad to think there’s a kid suffering in the middle of this and this crap has been their whole life so far. Forget about the details, break up and focus on healthy relationships and good parenting.

This 100%

nutbrownhare15 · 28/03/2025 22:02

It sounds like he won't move past this and I'd be ending it. Life is too short.

ExtraOnions · 28/03/2025 22:02

Not sure why you told him, you weren’t together, it was a one-off, you decided not to persue it.

Anyway… for whatever reason you told him, and he’s going to use it as a stick to hit you with forever.

it will be brought up in every argument, in every fall out, used an excuse to control your behaviour, used to stop you going out, seeing your friends etc.

Whole thing is doomed.

BIossomtoes · 28/03/2025 22:03

It was a kiss when you weren’t together, ffs. Just call it a day, he’s clearly looking for an excuse to end it.

BakelikeBertha · 28/03/2025 22:04

OP you were completely entitled to kiss, or even have sex with someone else if you felt like it, when as far as YOU were concerned you had ended the relationship. Just because HE chose not to 'see it as a real break-up', that was on him, not your responsibility.

If he can't move past what has happened, then he needs to end the relationship, not use things that happened while you were NOT in a relationship, to beat you with. He is being very unreasonable!

If you 'abandoned him during the worst period of his life', presumably it was because you could no longer stand being with him, for whatever reason. People don't end a relationship if things are going well OP, you had a reason for it, and he clearly wasn't innocent in what happened, ill or not.

As for ONE kiss, two months after the relationship had ended, how do you know that he didn't do the same, but just kept quiet about it??

Stop trying to appease this man OP, he's being very unreasonable, and you would be foolish to continue to put up with it, he's trying to make you feel bad, so that he can control you, DON'T let him!

Delphiniumandlupins · 28/03/2025 22:31

Regardless of who is/was right or wrong, if he can't get over this you have no future together. Your child deserves a calm and happy life and you two are not going to achieve that living in the same house. If you separate hopefully you can reach a place where you value and respect each other.

CalmTheFuckDownMargaret · 28/03/2025 22:35

He’s fixating on this issue as if finding an answer to it will erase your problems and make the path forward smooth. It won’t. You’re both forcing an incompatible relationship to somehow work, which is why he’d made it clear you weren’t for him before the kiss happened. He wants comfort and a healed ego.

Loloj · 28/03/2025 22:40

YANBU but YABU to stay in this relationship. It isn’t fair you or your child.

He’s using the kiss and the messages as a stick to beat you with - to detract from the things he is clearly doing wrong in the relationship. (Not suggesting you are perfect either).

This is not a healthy relationship and unless something drastic changes then it will not work. And by drastic I mean full commitment and building trust from both sides and for him to no longer bring up the past (which he won’t do by the sounds of it). Along with therapy and relationship counselling that you are both fully committed to.

I think you know the answer OP. You would be better off ending the relationship and focussing on you and your child and working on an amicable co-parenting relationship.

Pleatherandlace · 28/03/2025 22:41

Why did you tell him about the kiss? Why did you tell hime about the two
benign text messages? I think you love all the drama. That would be fine if it was just the two of you but there are is a child involved. You need to grow up.

OneShoeShort · 28/03/2025 22:41

Why? What in god's name would make you think this was a good idea for anyone involved or fair to your child?

He shouldn't be trying to "get past" any of this and neither should you until you've split permanently and do the moving on as two separate adults no longer in any form of partnership or romantic relationship.

Absolutely bat shit the both of you.

Tourmalines · 28/03/2025 22:52

you didn’t go and see him when he was hospitalised. Not once . You hate him . The only one I feel sorry for is the child .

Bex5490 · 28/03/2025 22:53

Sorry @AIBUornotttt . Nobody on here can say whether you were right or wrong to cross a boundary within this relationship because the relationship itself doesn’t work.

Can you honestly hand on heart see this relationship becoming calm and stable ever? Don’t you want a peaceful life?
