Maybe you are right, maybe not. Personal experience for you may not hold true for everyone. But I guess if this thread has proven anything to me is that I definitely don't want to break up with her, even if her past does bother me (although it shouldn't), now that I think about it. And about her past giving away her future, all it tells me right now is that she likes sex (I don't mind that), not necessarily that she will go for another guy quickly. Although maybe I'm just in denial :P
