Too scared to make a move?

Ok well, there's this guy who is one of my best friends, and he says he's in love with me but hardly ever speaks to me in person, only on IM and texts. A while ago he hooked up with this other girl I really don't like and they went pretty far. He's still a virgin and so am I. I got insanely jealous of this girl and was just angry at him for not noticing how upset about it I was. He knew something was wrong, but not that it was about him. It took me some time to realize that I actually did have pretty strong feelings for him which I had been suppressing because he is my best friends ex. Anyway, I told him I was jealous of the girl and he ignored it because I asked him to. He then started to stop talking and hanging around our friends and I got really worried. There was about three weeks of constant crying about it, which is ridiculous. Eventually I talked to him (online) about it and he said he didn't want to be around me because I'm not good for his heartbeat. After a while I told him how I felt but I couldn't be in a relationship with him for many reasons. Everything was ok for a while and we were slowly becoming friends again, but he has also made all of these new female friends who he spends more time with and I can't help but feel jealous. Then last night he suddenly got angry at me, saying that I'm just making things harder for myself by convincing myself I love him, when I don't. I'm so confused because I was in so much pain about him and now he says I'm lying to myself about my feelings for him, and I have no answer. I feel nothing. If there was anyone I would ever want to spend my life with, it would be him, but I'm only sixteen, it's ridiculous to think about that at this age. I want to try and talk to him in person, but I am way too scared. And I'm not even sure what I'm scared of. I know I'm worried about my best friend, being his ex and all, and also that I have no sexual experience whatsoever and he does. Any suggestions?
