How to change my uncaring and selfish hubby

Dear sir /madam. I and my husband are married for almost 12 years. we got two children -one is 9 years old and the other one is 8 months. my husband is very dominating. since I get married I never heard any single word of love and affection from him. He is very difficult to please and never happy. Even for small things he makes drama at home. he never bought me a gift as a token of love. when he was in a good mood i had mentioned about my feelings to him several times but he never took it seriously. He is a very selfish person. He only thinks about himself and his convenient. I am really fade up with his behavior. These days I don't talk lot with him. And he doesn't talk to me either. I had a big hope that after having another baby he will change lot but to my badluck he is becoming worse. He doesn't help me on household job or any other work. I am really very very unhappy. I have no one to share and express my feelings and he doesn't listen and care about me at all. If I mentioned something like this, he starts to fight with me. He always wants to win and even if it is his fault he never realizes his mistake. For each and every thing he blames me. I always cry quietly. I am working mum. But now for one year I am full time mum. very soon I am going back to work and I am worrying how would I cope with all these after i resume work. I am having too much. most of the time i cry quietly. As i already got 2 children,i never think of separation but i don't know ho long my life goes like this. i tried to talk to him so many times but he doesn't wants to listen. If i write and left for him to read, he wouldn't read. i don't know what to do? how to deal with this type of person
Sincerely ashmi
