Paranoia??

Hello everyone. So I have been with my girlfriend for a little over one year and we have had our tough times but now I am unsure whether I should leave her or whether I should stay together with her. We got together at September last year and at March-April this year she was on this trip to Berlin with her class, the trip was four days. When she comes home she tells me she have been together with someone else during the trip. After a few days she asks me if she could come back to me and I let her because I loved her very much at the time. No longer than a couple of weeks to a month later she got together with another guy and had an afair with him (no sex). I let that one slide as well. Then she promissed me never to talk to the guy and a few weeks later she got back together with him and they were a "couple" for a few weeks. Then she crawled back to me, stating again that she would never leave me. By that time she had told me 3 times that she would never see that guy again, but I let her in again (Dumb and stupid me). Everything seems to be fine now, but during these last few weeks she had become friends with this guy again and they have been meeting up once or twice every week, I see her 3-4 times a week since I live outside the city. But now I get confused because she had begun to delete her messages (Skype, FB and SMS) she gets from this guy and many other people, and now I get the impression that she might begin to be getting back together with this guy and my fears right now are that I don't want to break up with her, but I am not sure whether I want to be with her, I still love her and all, but I am not sure whether I should break up with her of the fear that she might get back together with that guy (Which she has promissed me that they don't even want to), or whether I should start asking around to make sure of my paranoia like instincts. Can anyone give me something to go on or to debait on.

I suggest maybe you should move on. For a relationship tho work there has got to be trust. She had broken that and doesn't appear to be making an effort to earn it back on top of repeatedly lying to you. I think she us taking advantage of you and i commend your effort for trying to Get past her cheating. Move on and maybe sge will grow up and give you the respect you deserve. I know it will be tough but you deserve better. maybe you are just paranoid this time but she should giver you the respect of not putting either of you un that situation again.or at least your feelings about the situation.
