My GF is really bothered about my past with other girls. She loses hours of sleep, feels like throwing up, and says she wants medical help to help her get over it before it ruins the relationship or pushes her away. She keeps thinking of images in her head of me having sex with other girls and says she cant stop. Her friends cannot help her as the relationships they are in, they lost their virginities to each other and whatever they say doesnt make her feel better. She cries when she knows im going out. She is from a very strict conservative background, i took her virginity etc and we have been going out 9months.

I know sexual preselection gives girls tingles, but this is eating up my gf, to the point i think its more jealousy than love/attraction. I come from a much wealthier background than her, and she has admitted she is a bit jealous of my material possessions. She also gets upset when she sees other friends of hers getting spoilt rotten by their boyfriends.

How can i help my gf to get over this? I dont want her getting brainwashed by so called relationship experts. I didnt think this affected girls like it does boys. Do girls worry about their bf's past?
