So here is the situation: I have been dating this girl for three years and I do love her and want to marry her. However, recently we have been talking about sex. We brought up the number of people she has been with and it's quite a few. A lot were just one-night stands or fuck buddies. Well, my problem now is I am second-guessing this relationship. Most of the men she met online and I kind of feel she is a slut now. I do believe you cannot judge someone by their past, but now I'm just second-guessing if this is someone I want to be with forever because I look at them differently. Any advice on how I can get through this?
