Why does my husband treat me badly?

My husband and I have been dating for 10 years total...6 of the years, we've been married. We first got married, he was amazing...bought me roses, without needing a occasion, always treated me good. Now, he doesn't tell me he loves me, I always ask first. If I'm sick, and we have plans, he gives me dirty looks and throws a fit, so we get into a huge fight. His mother and I do not get along. She has said a lot of bad things about me, and has picked on my family; as low as picking on my mother because she is in a wheel chair. So i refuse to talk to her. We do have a daughter, who is 15 mnths old...she does see her Grandmother. I have no problem with it. He always tells me to stand up and be the bigger person and just talk to his mother and sister and forget what they ran me down about and he's mad at me because we aren't talking. He says he isn't but he treats me like **** and gives me attitude and gets real pissy when he gets off the phone with them. The last two years...for our anniversary he never got me anything, nor got me anything for my birthday. He never even done anything for me, for my first mother's day. But, I make sure I do for his father's day, birthday, and our anniversary. When I was pregnant, he would put bills before us buying groceries so I Could eat. The whole 8 weeks I was off( c-section)...was a living hell. He was hammering me constantly about returning bck to work, finding a better job and allowing his parents and sister to hammer me also about going back to work early. He wanted me to return back to work right after I had her. He allowed his family to treat me like **** till I returned back to work. He's always picking on me, making me feel like ****. He calls me fat, doesn't help out and I don't know what to do.
