What should I do with the love thing?

This guy I love knows I love him. I did not tell him he just guessed. There is also this chick that told him that she loves him(he has known her for 3 weeks). Oh and he has seen us both naked on web. He says he cares about me and asks me why I love him when he is a bad person. I do not know if it is a short term thing he is going to go through or a long term thing with this chick. I know he likes her because of what he told me (which he regrets doing since I snapped). When ever I think of him with her I die a little inside. She sounds stupid too (she wants to get prego at 16 and be a doctor, and did I mention with his child?). He told me he loves me as a friend and a little more. I don’t know what to do. I think I may stop talking to him for a few weeks and delete him out of my phone and msn and hide his info in my room somewhere. I don’t know if I can though because I have tried to stop talking to him 2 times, but I can’t because I love him too much. This is no fair. I have crap luck in love and I am beginning to think that it will always be like that. :( Help? Advice? Wtf can’t he make up his mind on who to choose? What should I do?
