Girlfriend flirting with someone else

I will try to be brief. I am 46, my gf is a 37 single mom (2 kids)…few months ago she went to a club with some girls, i found out that she ended up flirting and dancing with some young guy of 21. Before i find out she told me that some guy came to her, talked to her while she was dancing, but she refused him and sent him away. I found out that she danced with him, i confronted her with this, and said “yeah, i forgot, we danced a little bit, few seconds, but that’s it”, and she swore that it was it. After a while i saw some videos made at that club, and i saw that she danced in an intimate way with him, several times, and spoke and laughed several times (flirting), and at some point she danced with him on the table, also in an intimate way (when i say intimate, i didn’t see any kissing, but intimate positions, grinding…etc). I confronted her again with this and she said that simply she forgot about that dancing on the table, because she drank too much that night, and the reason that she danced with him because we had a big fight that day and she just wanted to forget. The idea is, whatever happens we can talk about it, even if we end up cheating, we can discuss it, so i don’t understand why she still insists on lying. I am not sure if what i wrote makes any sense to you. But i appreciate your advice. Thanks in advance

@SUSIEDQQ, i am not sure i understand what you want to say

We all flirt sometimes in our lives and it's pretty harmless as long as we tell our respective spouses, partners etc without reservations or shame. Your GF went out with her friends and what happened is pretty inevitable given the place and the circumstances. She told you about it or rather told you what she remembered given the amount of alcohol she had drank. It's all down to you whether you believe her or not. You need to take your thoughts further though, and ask yourself why you guys are fighting because if her actions on the night were because of conflict with you earlier in the day, then you guys have some issues to sort. It's all good to be able to discuss things with her but you need to understand why these things are even happening in the first place. You don't mention what sort of a relationship you guys have but you need trust in your relationship together and going by your post, you're having a few doubts. You need to listen to your gut rather than your thinking.

You posted this on another forum a little while ago and you still haven't let it go. Regardless of many people trying to assure you that it meant nothing and that she didn't cheat, you are still obsessing about it. I can totally understand why she needs to go out and get drunk to forget things. You are obsessive and absolutely relentless. She didn't do anything bad. Get over it already.
