How to handle my boyfriend situation?

I've been dating this guy for 6 months now, we dated back in 08' so ever since I've been inlove with him. Hes great and all but, he has some issues.; He gets mad at me really easily, hes always playing xbox, hes always horny and replying to my IMs or texts 10 mins later, he says that I'm always a b*tch to him, he's hurt me sooo many times in the past. I'm kinda sick of him. Today I woke up at 7am, and I checked my IMs on my phone and he was STILL playing xbox.. its getting too obsessive. But I cant talk to him about it without him being mad? btw, im 15 and hes 16 and doesnt goto school + im afraid he might get taken away and I dont want that, help?
