Scared she's going to hurt me
apologies if this post is lengthy,
I am currently in a relationship which started 12 months ago, our relationship started quite badly as my girlfriend was actually in a long distance relationship when we met, I think we instantly connected and grew very close, I told her that I really liked her and that we’d only be together if she left the guy she was dating, anyway she couldn’t leave him and we just got closer and closer. We eventually slept together while she was still dating this guy, well I knew this had been a mistake, I’ve never seen such a devastated girl the next day, she sat at the side of the bed with her head in her hands and just said in a tearful voice, “I’ve never done anything like this before, how can I even look at him again” she looked like a train wreck, I felt terrible and rightly so I had helped her cheat. Well the next time she met this guy she was dating she tried to break up with him, but he begged her not to so she didn’t, but the damage was done and she eventually just broke it off a few weeks later. After breaking up with him we started to get friendly again and I soon asked her if she’d be my girlfriend and if we could be official, she said yes. Well things are great and we’ve had a lot of fun, I believe she is very honest and I’ve seen how guilty and sensitive she can get, and I genuinely believe she wouldn’t want to hurt anyone. Now comes a new problem, she’s going off on a surfing holiday for 2 weeks with some people she knows from a while ago, one of whom she had drunken sex with when she was single, I only know this because I asked her if she’s slept with anyone she was going with and she told me, my heart sank and said I wasn’t happy, she reassured me that nothing was going to happen and that they were just friends and it was a drunken night when she was single and that she’s committed to me now and is happy that way. I want to believe this and love her but I am petrified that she’ll hurt me when she’s away having a good time with this guy, I’m trying to hide how concerned I am from her because I believe that she will find my insecurity will drive her away. I’m holding onto the memory of that morning after she cheated and believes she doesn’t want to put herself through the same agony again. I understand that I am powerless to stop her cheating and the saying once a cheat always a cheat but I love this girl. I really don’t know what to do...
