Cheater

My boyfriend is a cheater, he took everythig away from me and all i do is offer more. He was once a good person then he started acting strange. He broke up with me reccently and i cant feel anything. im numb. yet the inside of me also feels like a knife is stabbing me and an elephent is constenly sitting on my chest when ever i think of him. He has called me everyname under the sun, left bruises that i told were form cheer he called me inmature when i said i wouldnt hjave sex with him and then threated to never talk to me again so i fanilly had to give him what he wanted. He told me that he loved me and a few minutes later would hit me. I still love him but i am woundering how much is enough? God says that you need to love everyone and that love is patenent, but how long is too long? I am still waiting fro him to change but honsetly i dont think he will. Or mabey he will and he will relaize the mistakes that he made but should I stay and wait for a day that might never come or what? I love him more then I ever loved anybody yet he has hurt me more the anybody has hurt me(and thats saying alot since im a foster!). Without him who would love me, even when i cant even love myself? But has he actua;;y loved me? I honstely dont know at this point in time
