I have been dating my boyfriend for about 2 months (we have been apart for a month of it though). We have a lot of mutual friends, and I've been enjoying my time with him. He is my first official boyfriend and I am still figuring out how it all works. Recently I have been hearing some really bad things about his past with other girls (not so great things about he teats them, especially when it comes to sex...nothing violent or anything, just being a thoughtless jackass. He has never done anything bad to me and treats me very well, but these facts about him worry me. I know he is way more attached to the relationship than I am and I feel like my guard is going to be up now. Should I listen to our friends?
