Do bisexual women think its okay to cheat on their boyfriends with other women? I was with a bisexual women and I was devastated when she posted pictures of herself making out with another chick on mypace. I hated her so much after that because I was so faithful =(

Now I'm scared to date a women who just might be "bi" cuz I think she will cheat, or am I being paranoid. If bisexual women think its ok to cheat on their boyfriend with another women can you please to me why?? PLEASE don't sympathize with me and tell me your rationale for cheating please!!!! I need to understand, because it doesn't make sense to me.
