I need advice

So my husband tells me to give his mom $500 to help with bills so I did. He just called and yelled at me. Why did you give her $500. Where did you $700 pay check go. Well I give you $100 and your mom $500 and that left me with $100 to buy hygiene and prenatal vitamins. My money is gone. When I help your mom you get mad and when I don't you get mad. There is not happy medium. I never win in this relationship. I said should I just leave and never come back? I told him I never spend my money on myself. I told him i need to biy bigger clothes because i am 20 weeks pregnant and my clothes are going smaller. He told I am a fatass. I told him i could give him anymore money because he is using it for his addiction. What will happen if i have baby? Will i have money for the baby? I do not think I want this baby any more. I want to give it for adoption because i do not my baby tp be in environment like I was when i was little. Watching my father beat my mother and watching them do H. Please give me advise!!!
