My sexual history is pretty tame compared to most and I sometimes date women that have had a much different past than mine. It brings up discussions because I am curious and I sometimes feel turned off by girls have done even years ago. So right now I am seeing someone that has been open and honest with me and I am wondering if I am being paranoid or if I have realistic concerns? While she was in college her best friend was dating a guy and they later married. She is still best friends with this girl. While her best friend was dating him she and the bf had a drunken night where they had sex which turned into 2 years of nsa sex. The best friend still has no idea and the girl I am dating had a huge amount of guilt over the situation. She says even if the guilt kills her she would rather live with it than tell her best friend and ruin her family (husband and kids). In turn this girl has low self esteem and also at one point she claims it led to an eating disorder. I do not support ruining someones marriage or life, but at some point I think the truth needs to come out. Any opinions?
