30M Some guy kissed my gf 29F

Me and my gf have kids together and have been together for 6 years . She was sober for about 3 years because alcohol used to be a big problem for her and she got a job at a bar about 9 months ago and started drinking again about 3 months into working there to give a little back story .

She was acting strange for a while and I kept thinking something was wrong with me and I kept asking her what was going on with her and she would constantly tell me nothing was wrong and she asking very distant and doing things to almost self sabotage . I feel like I’m going to miss a lot of parts of the story you guys might need but I’m going to do my best to keep it short and sweet.

I ended up seeing a picture a picture of her and “some random guy” I’ve never seen before and they were standing very close together . Like very close and I asked her about it . The story came out little by little with a lot of lies that ended up getting told later on and I finally started getting more and more pieces of the story .

She told me this night she had gotten out of work and was finishing something up at her work and she would be be home . She ignored a few of my calls that night and came home about 10 . About a month later is when I saw the picture and called her out on it . She proceeded to tell me it was her friends friend who she has never met before that night and found out it was a lie and she wasn’t at work and she actually was with her girlfriend who was with a few of her friends and they had drinks at her bar . She finally admitted she lied and they left and went to a house party and told me that random guy from the picture “tried” kissing her at the bar . The part that really bothers me is that the bar was before the house party so chose to still stay in that situation and go to a house party with that person and the friends and that picture was taken after him doing that so it just doesn’t add up to me.

She was crying so much and was so apologetic and says she was drunk and didn’t know what to do and went to the party still afterwards cause it was her friend . Since then she has been sharing her location with me and has been 100x better with communicating on her own . She says he knew she had a bf and that’s why she left an hour later but she hid the entire thing from me until I saw the picture and then the truth started coming out little by little . Kills me to think of my gf of 6 years and mom of my kids kissing another guy and lying about the whole thing . She hasn’t drank since the day she admitted it to me and says alcohol always ruins her life and she puts herself in bad positions . It’s really tough for me to not feel horribly and I think about it a lot because I feel like there’s a lot of the story missing pieces and just doesn’t make sense. Like if somebody came onto you like that and you didn’t want it why would you continue to stay there around that person and then later on take a picture with them that just doesn’t add up to me. I’m sort of just venting here but I’m also looking for opinions and thoughts and if anyone has ever been through something similar. She’s the only person in my tire life that I’ve literally trusted wholeheartedly and I don’t think she would ever cheat on me . She told me that she was in a really strange face for that month afterwards because she felt so bad about it and guilty and really all she did was make me feel like I was wrong and feel like I was crazy which made me even more upset because he’s had this gut feeling something was wrong.

What do you guys think and would you guys feel the same way as I do.? It’s really hard for me to deal with this and believe there wasn’t more to it . It just doesn’t make sense to me, things don’t add up but maybe that’s because I’m too close to it and I’m very emotional about it .
