I just started dating this guy from the town next to me about 2 or 3 weeks ago. I'm 15 and he's 17. I like him alot, I like everything about him. Except one thing. He has a MySpace, and me and my friend were surfing it just because we were bored. Well, we found out that he had gone through about 3 girlfriends a month over the summer. He did and said some of the same things to these girls as he does to me. And these relationships were just happening earlier this month, so they weren't too long ago. And I don't know if they are still going on or not. My friend asked him about them, and he told her to tell me not to worry about it. I don't know whether to beleive him or not....and I don't know if I should just forget about it, or confront him. What should I do?
