What to do about my girlfriends extremely promiscuous past
I am 23 and my girlfriend is 22, I've known her since high school but we never really hung out during that time. About five months ago we started talking and dating. Everything was amazing I get along with her better than anyone else I know and we have fell in love with one another. She is an extremely sweet and beautiful girl and I consider myself lucky for being with her. At the beginning of the relationship we were talking about our past relationships and she told me she had two previous longterm boyfriends which account for her two sexual partners before me. Just recently I've heard from many of my close friends that knew her back in high school and they told me about her past. I was told the same things by many credible sources that she was a very very sexual active person. She used to have sex/oral sex to get into parties and also to get cocaine, she's had some threesomes that involved 2 guys and her, many boyfriends I was not aware of and that she cheated on everyone of them, additionally her and her best friend at the time would give oral together to guys along with many other things. I despise girls like this and she knows that I do and I always told myself I would never be with a girl that has no values. I have not confronted her on these issues yet and I plan on doing so after I get back from my military training. I do not want to hold her past against her but that kind of past I find hard to overlook. I do not know her reasons for why she did these things and wish she was upfront with me so I didn't have to her it from other people. I am a christian and I try to live in that way, I believe she regrets her past and about two months ago she was saved (baptised in the christian church) and she did this with no pressure on my part. She also wants to become closer to god and I love that about her. I feel I'm at a crossroads because if I stay with her we will become married but I'm not sure I can forgive her past and be able to trust her. I need advice on how to handle this or what to do?
