So i've been dating this girl now officially for about 7 months nows im 23 and she is 17 now im not here about the age difference and really dont want to hear about it. The parents are ok with it and in florida its legal, my issue has nothing to do with it. Problem is about 2 months after we had started dating i happened to be on her facebook cause she left it open on my computer and i saw a message between her and another guy where she was talking to him and asking him if he would like a **** buddy. Shes never met this guy before and when i confronted her about she said it was all just a joke and she was playing around with him and would never cheat on me. ofcourse after seeing this i lost trust in her. most of her friends are guys and since that day now i get really jealous about any of her guy friends and i dont trust her being around guys. We've talked about it several times and she apologizes about the situation and says it will never happen again and assures me that she will never cheat on me. she says she loves me alot and has recently done things to show her love, like she surpriised me on valentines day by waiting for me at my house in my room filled with candles and rose pedals. The other night she also surprised me by coming out to this club i DJ at un announced. I love this girl but ever since seeing that message i always have doubts in my head, and she has since let me see her text messages on her phone and i've seen recent facebook messages where guys have asked her to hang out and she tells them that she has a boyfriend who she loves very much. Do you think she really was just messing around with this guy and playing a prank on him or could she really be doing things behind my back. For the most part she tells me where she's at all the time and the people she's going to be with but i always feel as if she could still be lying to me. please help.
