<human>: Okay. So I'm supposed to be doing a paper, but this has been on my mind for a long time now, about a week. I'm the type of person that has learned to ignore everything and just not deal with it. Turns out that's not a good idea for this, since I've been in a pretty bleh mood lately, and overthinking this situation a lot which has given me intrusive thoughts about things totally irrelevant to this situation. Kinda just snowballed and made me overthink I was feeling blah when I knew I was just feeling bad about the details given to me.

Anyways, onto the story. So recently, I have started to question my girlfriend's honesty, and my trust for her. Reason being was that she told me a story about work one day, and just said some other story later that night. Which made me question past rumors I have heard about her. Her previous best friends, who are no longer best friends with her, told me she was with them one night, going bar to bar, and she was drinking a lot (she loves to drink). Later that night, she was touching these two guy's faces and letting them hold her by the hips. Keep in mind I wasn't there, but apparently this happened, both of her friends seeing her behave like this. We were 2 months into our relationship at this point. 

I confronted my girlfriend about it recently and she said it never happened. But I just can't seem to get over it. I don't know who to believe. I want to give her my everything, but I get stopped by this thought, right in my tracks. I really like this girl, and the thought of ending it with her sucks really really bad, but I don't want to stay feeling all shitty. This sort of thing has happened before in my relationship previous to this and I just don't want to do it again. Still, I don't know if any of the best friend's stories are true. 

What do I do?

Give me the gist of the text in a nutshell
<bot>: GF's old best friends told me girlfriend was physically flirting with 2 guys when she was at a bar, GF denies doing it. Am feeling shitty about it and don't know what to do.
