Isn't relationships about compromise?

I have made a lot of posts unclear, so I want to make this one as clear as i can. With the cons of bother of us. If you have any advice, please give it. And Please no ride comments.

Me- I get attitudes fast. I'm stubborn. I say hurtful things when i get really upset. I shut down instead of facing an argument Head on. I give up easily. I tend to feel like the victim allot. I don't communicate I don't show all of my love. And i pretend i don't care and show him a nonchalant attitude.

Him- He questions me about everything i do. He tells me what a horrible job i do. He talks to me any kind of way. He cheated on me twice (but he says its not cheating because he never met the girl in person and that he only talked to them. But one He doesn't admit he was talking to even though I'm not stupid). He is unreliable. He is irresponsible. He doesn't know what he wants. He never answer my calls but expects me to answer his. If he do call he yells at me. He isn't sweet anymore

We use to be happy we use to show each other our love. We use to talk and laugh for hours. He gave me the socks off his feet of my feet were cold and the clothes off his back. And I'm in turn I slept in a car with him when he was homeless.

I want the old us back. I told him i will treat him the way he wants give him what he needs and all I asked if him was to just be easy.(don't be mean when i do something nice, don't question me, don't catch attitudes so fast when I say something to him, and just be sweet) basically don't be an ass while I'm giving my love. But he says no either i change or we are through. He doesn't want to do anything but be an ass.

Im just wondering isn't relationships about compromise? I asked him that and he said no. I don't know what i should do.... can someone please help me....please..
