My last two relationships were abusive, I just got out of my last one. I really, really need some support right now.

I’ll try to sum this up with out getting into too many details, but here is a little bit of a background story:
We were together for about a year, he ended up moving in with me because we became so close. About 3 months into our relationship, we got in a huge fight, this is the first time he hit me, he punched me in the face then left me. I had to walk to the hospital about 10 blocks away and by the time I contemplated even going and got there, it was too late for stitches. I lied to the hospital about what happened.
I begged him to come back, I didn’t want to be alone. Since then we had periods of everything great and wonderful then really bad fights where he would hurt me. I hurt him back so I never thought the police would believe me if I called them. He was always so nice to me after it happened. The last month or so he became insanely paranoid I was cheating on him even though I called him all the time and I was at school (college) all day. One time he got physical because he thought I was cheating on him. Whenever I tried to break up he’d cry or threaten to kill himself and all the guilt was me.
He took me away from my school and my art, this hurt me the most. My work is my life, and he was making me choose. The last fight we had was the worst, I was afraid for my life. He was beating me over my head and back, grabbing my neck, then got a rope and stood there threatening me. I’m crying so hard as I’m writing this… I can’t believe I let it go on this long.
I got the courage to kick him out, my Father had to get involved. He took my puppy… I’ve been crying for days. He took my puppy just to hurt me, I love that dog like a child. I paid for him, but he signed the contract, so legally I can’t get him back.

The worst part is I keep calling him up… I want him to come back. I don’t want to be alone. I need some help, please. I lost most all my friends because he wouldn’t let me hang out with anyone, or they were afraid of him so wouldn’t come over anymore. I’m trying to stop myself from getting into a relationship with another guy too. I’m so lonely, I’m so depressed. I don’t want to get into another bad relationship and I don’t want him to come back. Please help me.
