My life is falling apart.. from boyfriend to best friend's!! Help?!?

I just moved here in october, well since then i've made a lot of friends and I gained a boyfriend named Scott Norris Goodman.. Here's our problem... Well I love Scott.. He means a lot to me, and he just got to where he's i don't know.. controlling I guess.. I use to be an emo kid.. Use to cut myself, hide away in my room from my family and friends, well he told me If he seen another cut on me then it was gonna be over.. I haven't done this but one time since I have moved here, well he also told me that if I ran away then I could forget about him, I hate my house.. the people in it irk my nerves and I hate it! If we can't see each other this weekend it's gonna be over and last night he wrote me on facebook and told me to stay away from this guy named Chance.. My friends have been chance's little play toys and I have been in the drama lately.. well my friend told me that she had with him.. well her other friend had with chance too and she's also my friend and I though she should know, I mean my friend that had him first had the right to know that her ex friend was ******* her ex play toy, well she wanted to be more than just his play toy and he wanted to date her but after a while she got tired of waiting on him and finally told him goodbye and he moved on to her friend and they've been at it ever since then. Well anyways back to me and Scott, he told me not to talk to him and I asked him why and he just told me that every girl he dates and has with chance gets them to break up with him **** chance and then chance leaves them, me and scott are just alike and he means everything to me.. I told him last night I wouldn't talk to chance and he said good let me find out you do and I was like okay and i told him it was messed up that he's giving me all these rules or else it's over and he was like baby i'm doing all this because I love you and want to marry you one day.. and all I could do is say awww.. he's my everything... but Is he getting to where he's too controlling?!!! PLEASE HELP!!!
