Getting Depressed

I will try to keep this as short as possible. my 7 week old suffers from GERDs. She is also breastfed. my husband has had a hard time keeping her because she wants to nurse and not take a bottle. Sometimes my hours are late. He has been taking his frustrations out on me. He even told me today before he stormed off to bed that he wished I wouldn't have breastfed her. he constantly rushes me back from work to give her to me. during my maternity leave I felt like he didn't put in the time to bond with her. it was always I'm to tired. he has been talking to me poorly about my schedule which is making things worse as I'm already sad I started back work and can't be with her all day. He stated how his other children from his previous marriage never were this difficult. He assumes because they were bottlefed. I pump milk but she wants the real thing. He's been so mean and dry. I'm really considering leaving him. He's making me feel like he regrets her and I'm a single parent. This was a planned pregnancy. I understand that it can be hard and god knows I would love to be a stay at home mom, but my salary is the reason he can be his own boss and start out his business.
