Hi RJ! Please let me know if you were able to get past this and be the man she needs? I am currently going through this as I have a similar situation.. I've been molested by my brother growing up and lost my virginity by a painful rape and have been assaulted several times.. this led me to be very promiscuous in my teens and very early 20's. I've lost my fiancé recently because he knew too much and my past was effecting him in such a bad way. He thought my promiscuity was my own choice and doing when I don't think he understood or will understand what led up to it, he just see the actions and is disgusted with me. I've been with guys that he knows and he even found out the lowest thing I could have possibly done.. I sold myself once to an old white guy. This was all before we got engaged and now its ruined our relationship. All I needed was his support and love to get through this difficult time.
You can help by just listening to help reassure her that she is loved and you're not judging her stay by her side and be patient
