Drunken "mistake" by girlfriend

Well she cheated and she didn't want to admit it to you, in fact it's quite clear that if she could've gotten away with hiding it from you that's what she'd have done. Personally I think you should break up with her, it's unlikely to be the same now and you'll probably get hurt again later if you don't. But at the end of the day you have to do what you think is best for you long term.

Thing is though, with her hiding it, the conversation went along the lines of:

Me - So how was the party? Any gossip
Her - Not really, I don't really remember much
Me - Oh ok then (then I looked at her for a bit, then she was like)
Her - Actually, I need to talk to you about something...

What do I do?

Reasons to end things:
- she kissed someone else
- she tried to lie about it to start with, and may not have told you if your friend hadn't noticed
- you'll always be worrying about her cheating again, especially when drinking is involved and you're not there

Reasons not to end things:
- she was drunk
- she did "only" kiss him, and even then not full-on making out
- it was new year's eve?
- she told you and she feels guilty about it

Really, it depends on whether you feel you can trust her. You clearly believe she has over-stepped the mark, and have had this conversation with her so she knew (or at least would know if sober) that what she did was outside the boundaries of your relationship, so it this sense she was wrong. What you have to decide is whether the reasons not to end things trump the reasons to end things - in your heart, not your head. Relationships are about emotions, and so there is no real right or wrong decision.

Reasons not to end things:
- she was drunk
- she did "only" kiss him, and even then not full-on making out
- it was new year's eve?

The issue here is alcohol. Don't let this ruin something that is good. Alcohol brings the worst out in people. If she is genuinely sorry then I think you should forgive her. The guy probably coerced her anyway.

Anon please.

So on New Years I wasn't out with my girlfriend as I was working. She first came to my pub for a bit and then afterwards, they all went a house party. I could tell she was a bit tipsy at the pub and so I wasn't surprised when I started getting drunk texts and calls from her when she was at the party.

Anyway, at the party, she got too drunk and too "close" to another guy and at midnight she kissed this other guy. My friend saw this and so he told me the next day. I asked her if anything had happened at the party and at first she was like "I don't think so.... I can't remember", but then she told me the truth. She said they didn't french kiss but according to my friend, it still went on for a good 6 - 7 seconds.

Now I hate this so much. I feel betrayed, let down, whatever and if there's one thing I try so hard not to do and that's cheat because, well, I hate cheating that much. I believe that she is my girlfriend and so all intimate moments like this should be with just me (and she knows this).

Because of this, I feel like I should honour my principles and break up with her, but at the same time, I love her so much. I've had girlfriends before and she's the first person who I've felt like this about. I'd hate to lose her. But also, I don't want her getting the idea that these things are ok, and that she's gotten away with it or whatever.

What do I do?
