How to get my abusive boyfriend out of my life.?

Hello, I need some advice. This is my only opportunity to actually ask for any as he is out to an appointment. I have been in a relationship with any abusive man eleven years older than me for ten months. I have been abused in the past by mom and first boyfriend that I did not even realize what I had gotten myself into-again. I tried to leave and break up with this man nine times. He his verabally abusive, mentally manipulative, physically abusive and mean no communication skills. I am over his antics, the other day he hit me for the last time pulled both my feet from under me as I attempted to walk away from him when he was in one of his drunken-drugged stupors. I fell so hard on my back and neck that I am still in pain this day. I told him I wanted him out for good. He begged and pled with snot tears the whole nine. I said I will take you back but if you ever put your hands on me that would be it I will throw you in jail. The sad part is, is that he has a disease (addiction) that I am sure messed his central nervous system beyond repair. I feel bad for him, i do, but it is not my problem anymore. I want my life back I want to focus on myself and children again. Here is the dillemma. We just moved into a new house nine days ago. I want to keep the house as I can afford it on my own, it is four bedrooms and near everything -school, busses, store, my daugther's mates are nearby. The other day when I said I wanted it over, he tells me I could get out. He has plenty of money through inheritence, vehicle, familial support, plenty of resources. I have myself, my children and 2000 bucks a month. How do I in a nice way tell him out with our relationship and him out of our house? I told him I would reimburse him his half that he invested on security, rent, and moving expenses.(although he has stolen thousands from me for his habits) I just want it be easy with no courts etc although I am not afraid to have another injuction out on him. What do I do? I do not want him mad at me so he wont attack me on all levels. I do not want to be around him crying then attacking, and I do not want my kids exposed to anything else other than our happy family in our house Please help
