My Boyfriend Beats Me Up!!!

Yeah I said it out loud. My boyfriend beats me up all the time. He treats me so terrible, that I have planned on running away. My family and friends have no idea the hell i live in behind closed doors. I live in a really nice apartment complex and they banned my ex from the apartments. My apartment manager told me that if he is caught in my apartment again she will evict me for allowing him there. Well hello he has keys and the next night after all this happened he was sitting in my living room unpacking his things. He made the statement then that if i call the police he will say he has been there and never left, that way i will be getting evicted. I know i should leave and I plan on doing so as soon as I can save up enough money. Every holiday every birthday and just any week day I may get attacked. The fuel to the fight is this....... We broke up at the beginining of the year for about a week. I didnt waste any time, the first chance i got i went out with my friend girls and had a blast. That night I met this guy named Brian. He was great looking and really nice and pleasant to speak with. Thats as far as it went. Just a lot of talking. This is just what I wanted and needed providing what I had been through. Well in the mist of me talking to Brian my ex slid right back in to home base and I allowed it. But I never stopped talking to Brian. Brian listens to me and makes me feel really great. Recently my ex went into my phone and saw plenty of texting and talking between myself and Brian. He choked me and through me all around our apartment. So a few days go by and still I never stop talking to Brian by the way Brian knows all about the abuse and I confide in him. My ex found more text and talking between myself and Brian and he made the choking episode look like a cartoon. During my whooping I told my ex that im not afraid of him and I also told him that the he is trying to put fear in me and its not working. Im not sleeping with Brian and I like talking to him. AND I WILL NOT STOP. I asked my ex to leave which he refuses to do. I know the advice is to call the police, but here's the deal. He's not on my lease and if the police come I will lose my apartment and where will I go?? Thats why im saving my money because i know im gonna have to leave as soon as I can, before i get killed. If i was sleeping with Brian or if I was speaking to Brian about things that are considered cheating I would not have even wrote this blog. Im going to run away very soon. I cant take this anymore. thanks for listening I had to tell somebody!!!
