My boyfriend just doesn't care?

My boyfriend and I have been together for almost 3yrs now and we have been living with each other for about 2yrs. Whe we first met each other he was going through a divorce which was taking awhile and he was going thru alot of emotional stress and financial. We took things really slow at first. Whe the divorce was finalized we started getting more serious and we got a place together. It was hard for awhile becauase he took the anger he had on his ex out on me. He would lash out in anger when he had an argument with her or if he had to pay the attorney and wasn't left with much money he would take his anger out on me. (of course i did give money for some of the bills) he was jst mean to me. he would leave to go help his best friend who was girl move and didn't get home till late, he would curse at me and he would ignore me. i would try to make up with him but it wouldn't do any good. he would try to make me fell guilty if i was too tired for sex and then just storm out of the house without saying bye to me in the morning. if we had an argument he would tell me to leave and move out, twice. Well after about 8mnths he started changing a bit for the better, so i thought. I have always treated him good and as well as his kids. i clean, cook , do laundry, pay bills, make his lunch every week day morning and see him off to work and see the kids off when we do have them. He just doesn't care about my feelings it's always about his. if i'm having a bad day he says things like so have i or he'll accuse of something and make me feel worse. i got myself a car the other day because nothing we have is mine or in my name, the apt, the cars, nothing. so i wanted something that was mine, that i worked hard for. and if he were to throw me out again i would have a way to get to work. but he got made at me about getting a car and thinks i just want to leave him. i don't want to but i can't continue to arguing and him being insensitive, he doesn't hold me when i cry, he isn't romantic, he doesn't just tell me he loves me just because, he gets mad at me if i'm mad. everything is always about him and he always makes himself out to be victim. it has been about him for 2yrs now i want to be thought about. sometimes he tells me "then maybe i should just worry about me and the kids" what is that? after everything i do he tells me that?1? i have never turned my back on him ever but he has turned his on me. i wish he would change but i know if hasn't by now he won't. I don't know what to do.
