Okay so I have been dating this girl and she is a year younger then me, I am 17 she is currently 16. We met last May and have been going out since, she is extremely good for me she is always there through whatever and has dealt with me at my worse. I feel comfortable enough to do anything with her so pretty much I find her to be perfect but there is one problem which haunts me every single day and has brought me to a point of really low self esteem. The thing that haunts me constantly is that about two months before me and my girlfriend met she was going out with this kid who was a player and was known by everyone in my school and on Facebook to be one. He basically uses girls for sex and leaves them, which is exactly what he did with my girlfriend except he took her virginity, had sex with her one more time and broke up with her. From what I know she was really into him and in the beginning of our relationship he was constantly brought up. This kid had money and dressed extremely nice, he was known for goodlooking and all these other things he has gotten with so many girls that I am cool with and I know. I think about this everyday because my girlfriend lost it to him and I feel extremely sad because I can never have the chance to have her virginity which is really important to me. I have become insecure due to her ex I constantly think about that moment and I even sort of lost a sense of personality because that just stresses me so much. I really don't know what to do I feel insecure and low about myself and think he was better then me. Please give me tips on how to deal with this.
