breaking up and moving on with my life?

I have been with my boyfriend for 10 months, and i think I'm just ready to move on. I love him very much but i don't feel physically attracted to him anymore, and i defiantly am not interested in having sex with him any more. We have had a good share of arguments and he has been emotionally abusive to me a lot, even on good days! We have been living together for about 4 or 5 months (in his parents house) and every time something goes wrong the first thing he tells me is "get the f out". About 4 days ago he told me to leave, and i was just so over everything so i stared packing. I was packing up my stuff as he yelled horrible things at me, then he told me i couldn't leave. We fought and screamed at each other and finally i got all my stuff in the car and left. 1 hour later why am i calling him trying to work things out? Now im back at his house regretting calling him (and of course now hes being nice making this even harder) I know leaving him is the best thing i can do and i know this isn't healthy, but it hurts to leave the one you love, even if its for the best. I'm pretty sure there is no fixing this relationship considering something like this happens on a monthly basis. I'm ready to move on and be happy but I'm not sure if I'm ready to be alone.
