here's my story
i was raised in an physical,and mentally abusive household. i remember going to school and being picked on all the time. my mind was messed up, so my happiness was in men. i was young and didnt know how to handle it.
when i met my son's father he made a comment about he didn't like the fact that "all those men was all up in me" knowing he has been with twice the women than i've been with men.
i dont care what anyone says, but from that point on i do not discuss my past. i had post traumatic stress at thoes times and it's hard dealing with someone judging you. i m an over sensitive soul anyways.
i understand how you feel. and i think it was wrong when your chick hung out with the guy that was your friend knowing she has slept with him at one time.
i dont know her background, what she's been through, or why she did what she did.
i feel like you should be forgiving of her mistakes like the bible tells us to be. if it was too much for you to handle then you werent the right person for her.
i just hopes she learned from the mistakes she made and not repeat them.
i also noticed that the younger guys are more judgmental about stuff like this. my current b/f is 18 year older than me (he's 51) and he is very forgiving and totally in love with the person that i am.
