Should I tell my partner about drunken kiss with a colleague?

NC’d for this.

Ahhhhh I’m really feeling anxious atm. My own fault I know. I had a drunken kiss/grope with a colleague on a work night out on Friday. Woke up the next morning feeling regret but thinking I’d just forget about it. Now I can’t help feeling so much guilt and that I should tell my long term DP.

Do you think if I just try really hard to forget about it, or fess up? And be clear it meant nothing and I had far too much to drink.

Would you want to know if your DP had a grope and a kiss with a colleague?

No

Yes you should tell him because he deserves to know and if he finds out from someone else it will be a lot worse. But if I was him I would dump you.

DannyDeever · 26/03/2026 16:12

Say nothing. Try to forget it. Don't do it again.

He won’t find out from anyone else, our other colleagues had left by that point.

Unless he is likely to find out, I’d jut shut up. Put it behind you - and don’t get drunk. 😉

SpaceRaccoon · 26/03/2026 16:12

Don't tell him, it'll just hurt him - carry that guilt and remorse yourself as your punishment. And re-evaluate your drinking.

Jellybunny98 · 26/03/2026 16:15

I say tell him purely because I would absolutely want to know if my husband did this. I don’t think it’s fair to withhold information from someone that would potentially make them end a relationship.

Buscobel · 26/03/2026 16:17

What do you think his response would be?
Do you want to stay in your relationship or pursue something with the colleague?
Are you feeling that the guilt will be assuaged if you tell him?

If you’re prepared to sacrifice your relationship to make you feel less guilty, then tell him. If it really was a one off drunken incident and you care about him and want to stay with him, don’t. You might feel less guilty, but you’ll have made him feel bad. Keep the guilt to yourself and vow not to do it again.

rubyuggs · 26/03/2026 16:17

If you had slept together then absolutely yes, you should tell him but for a drunken kiss? no, I wouldn't tell.

In my opinion this is one of those small things that could ruin your relationship forever and its not something you are likely to repeat if you are feeling this upset about it.

WonderingWanda · 26/03/2026 16:21

I've been with my dh for 26 years and despite many drunken nights out with male colleagues I've ever accidentally cheated. You need to have a really log think about why you did this before blowing up your relationship. Yes your parter deserves honestly but that is likely be the beginning of the end. Is that what you want?

Netcurtainnelly · 26/03/2026 16:23

So you want to make yourself feel better by offloading onto him.
Don't bother. Don't get drunk when out though without your partner.

OriginalSkang · 26/03/2026 16:23

You should definitely tell him, but be prepared that the relationship is probably over or at least will never be the same again

Sartre · 26/03/2026 16:23

If there’s absolutely no way of him finding out down the line then I wouldn’t. It isn’t worth fucking a marriage up over a drunken kiss, just obviously don’t repeat it!

OriginalSkang · 26/03/2026 16:23

I don't think you care much about the relationship, or it wouldn't have happened

AStonedRose · 26/03/2026 16:25

Jesus. Of course you need to tell him. He needs to know his long-term partner's cheating on him.

If you don't tell him, this will eat you up.

dadtoateen · 26/03/2026 16:25

Flip it round, if he did it to a colleague would you want to know?

Yes, he should be told

AStonedRose · 26/03/2026 16:26

It may be a good idea to look at your drinking too, OP, if you're losing control to this extent.

Eightdayz · 26/03/2026 16:27

So many hypocrites when the shoes on the other foot.

Sure. Dont tell him. Enjoy living with the guilt.

Randomlygeneratedname · 26/03/2026 16:27

I think you need to think about why this happened too, I have been in some horrific states when I drank but never snogged anyone else.

AgnesX · 26/03/2026 16:28

This is the third post in as many days with posters doing something with someone who's not their partner.

Go right on ahead if you want to cause a fight (at best) or your life to implode (at worst). Seriously, what good do you think it'd do.

Boomer55 · 26/03/2026 16:30

It was a kiss, not sex. Just get on with life. No one is injured, no-one is dead. 🙄

ChickpeaCauliflowerSalad · 26/03/2026 16:31

No, don't tell him, it's not fair on him. Learn from it & either leave him or resolve not to be such an idiot again!

This.

If your DP kissed a female colleague would you want him to tell you or keep it secret?

I don't care whose foot the shoe is on.

if it's a one off stupid thing then burdening the partner with it helps no one, the idiot needs to learn from it & make some decisions to either leave or not put themselves in that position again.
