Sorry for the length of this but If anyone can give me some advice on this situation I could really use the help. I usually give my girlfriend alot of freedom when it comes to going out with other friends but it definitly takes a toll on me whenever she goes to vegas. Over the past 6 months she has gone to vegas with her friends about 5 times now and everytime she goes im at home biting my nails knowing what goes on in vegas and hearing the jokes from all my friends saying "oh man shes so cheating on you lolololol". Finally though the last time she came back I had to dig into her phone and I saw a bunch of phone calls to other guys she met over that weekend and text messages too. Mostly nothing too bad except for this one guy telling her to come up to his room but i didn't see much follow up from that and she claimed she never went there. What really sucked is that we had gotten into an argument about it and in the middle of the argument some random guy from a blocked number called her and she played it off like who is this? I don't know you! and the guy's like "wtf are you serious?" then is like "whatever" and hangs up. I should of just walked out on her but I didn't. We have a good relationship but the only thing that makes us argue is when she goes out on these lavish trips with her ho train friends which is why i did'nt break up with her over my anger about getting the guys numbers in Vegas. She said most of the guys numbers were bouncers in clubs to get them in which I believe but there were a couple other guys that were texting and calling back and forth that made me suspicious. I think I may be nieve for thinking she didn't cheat on me but whatever. She leaves again for one of her other friends birthdays in two weeks and I am already dreading it. I don't want to be the psycho boyfriend that tells her she can't go because I do what her to have fun and I don't wish to be controlling, but I feel that after what happened last time I don't have confidence in her going anymore. I told her this and told her that if she goes I want her going knowing that it really hurts me when she does go. I don't know what to do, it really hurts me so much when she goes that I want to break up with her. Any advice would be much appreciated, im stressing over this badly.
