WTF?!

I've been hurt so many times it took all off my courage to go out with my gf. I know I like her but I always have the feel that I'll be abused by someone I trust. I can't even rely on my folks! All I have is Rei and my bff Ashley. Then I thought no I have a gf now I can confide in. That was until last night she started telling me how she use to abuse (literally) her gfs. Well we don't live by one an other so I have that comfort and I'm built like a linebacker so issues there. What scared me is when she said she hurt girls just to feel better about herself. Now she says she sorry about it. I believe her... until this is sent to me by her ex (I blocked out names)...
