Flirting with his ex...

I've been with my boyfriend for over 2 years but have been best friends with him for much longer. I am his first everything really, but there was this one girl who he 'thought' he loved when he was around 15 years old.. as i was his best friend at the time, he told me everything he thought about this girl, and now being his girlfriend it made me very self conscious and jealous of her... so much so that i told him he couldn't speak to her anymore. Anyway, about 5 months ago, he went to his friend's party in a bar, and this girl was there. When i asked him if he'd spoken to her he said no, and that she was sat on the opposite side of the room. However, yesterday it came out that apparent;y 'she was sat very close to him and they had their legs intertwined, whilst he had placed his hand on her upper leg and was whispering in her ear.' Upon questioning him, he admits everything other than them touching. However, as he initially lied to me about even talking to her i just don't know what to believe. Im trying to move on but i can't stop picturing the scenario in my head and i know if i don't stop with the self-torment the relationship can't go on. ANY help would be appreciated for the sake of my sanity!!!! should i drop it and move on?

You should believe that this girl is out to get your BF and your BF is apparently allowing her in. I would not trust anything he said about this situation. I wold make it clear that he is no way to meet./contact/text with this girl again. Placing his hand on her upper thigh is " touching". Intertwined legs is pretty close. Believe what your gut is telling you. hat's the odd that this girl just happen to be there? Why weren't you at the party??

How did it happen to come out that scenario wasn't as first reported? How did you get this blow by blow account? "he admit everything but them touching" He gave this girl he's open to whatever. Has he seen or been with her since this party? Are they texting?
