My husband treats me like a slave

We both work full time jobs. I am a teacher and he is a police officer. Whenever he gets home from work he sits in his chair and watches tv, expecting me to wait on him hand and foot. I do all the cooking, cleaning, and I change all the babie’s diapers. He never helps me with the baby. He tells me that cooking, cleaning, and child care are all my job because I am a woman. I told him that it is not fair that I have to do all the work around the house like a stay at home mom but also have to work full time. He said that it was my dutie because I am the woman and any woman who cannot work and take care of her husband and family is not a “real woman”. I am starting to feel like more of a slave then a wife. All this work is taking a toll on my physical and mental health. I have lost a lot of weight and I barely have my period anymore. I never get to sleep because I am awake with the baby all night while my husband sleeps and then I have to work the next day. I do not know what to do. I love my husband but I am starting to wish I never married him.
