I need some advice dealing with my girlfriends past. Breaking up with her is not an option. We have a 7 month old girl and I need helping getting over it. It is my problem and not hers. Thoughts of my girlfriends sexual past which I think is very promiscous creeps into my mind every now and than and it is killing me. She is not the same girl as she used to be but her past is disgusting to me. I don't know what to do.
