Ughh idk wht to do. please help im desperate for advice!!?

Alright so I got to know this guy on a monday and we liked eacother until he asked me to be his girlfriend on a wednsday. So i said yes but i asked him to see if we werent going to fast and he said he was fine with it. So i went along with it and you know enjoying it until he broke up with me on a friday. He said he felt pressured and I said i felt pressured too but of course being a girl i teared up a bit and then i saw him flirting with other girls. I was actually gonna open up my shell and try hanging out with him and holding his hand during the fire works and tried you know being open. But he also broke up with me beuz we barely tlked and i was like ok. So then we were like lets go back to the way we were before he ever asked me out. So i agreed but he never did anything! im the one who actually tried but whtever. So then i see him one day and he was flirting with me like crazy and i just went along with it. But he still doesnt txt me or anything. So idk wht to do know. He also has a myspace and he knows that i do too but never added me. He also was flirting with me crazyingly that day but didn't hug me or anything like he did to my friend. He also went out with this chick that looks like a guy for like two days. So i think he was doing that just to make me jealous. And it was kinda working. So now im really heart broken and I think the reason why this is all happeneing is becuz of his loser friends. They always tell him wht to do. Like the day after he said for us to go back to the way we were i hugged him and idk whether if his friend was being a or he was mouthing them to get him away from me. After that i never did anything. I havent talked to him since. So please give me the best you can. Ill add more details if you want if this is unclear....
