My husband has been mean to me since I lost weight: Advice?

My husband is so jealous. I recently had a gastric sleeve. I was never fat before kids, but after our twins, I was huge, so I had surgery recently, and I’ve lost over 100 lbs. I’m taking better care of myself, dressing cute, and doing my hair and makeup. I’m finally happier. But he is acting crazy. We’ve had so many issues because he’s mean and hateful. He used to say mean things about my weight and just about me in general. I’m the only one who works, and he leaves me all the work at our house. I want to leave him, but I’m so scared because childcare is so expensive. Does anyone know how to get through this? I feel so alone. I don’t have anyone to help me with my kids. What would you do?
