In your opinion, will she be loyal?

She has "been with" some other guys, is a fast mover and an easily turned on girl. She has said, however, that I am far greater of a person in her eyes than any other she has dated and that she has done her time in dating and wants to settle down. We are going to wait till marriage before anything ual. I just have had a hard time getting her to be committed to staying -free and I see that she is easily tempted against her set goals. I want to know that trust will be there for the entire relationship. As I think of her drive for I realize she is not so different from many other girls and I can't blame her cuz my drive is through the roof. I really just want her devotion to be to a happy and faithful marriage and I love her so much that I want this boy crazy girl to experience a meaningful relationship that will really last. Statistically a marriage that had happen beforehand is so much more likely to end and I don't want that for either one of us. Please tell me your opinion.
