Husband being a jerk...

Hi mommies and mommies-to-be,
I don't know where to start... I gave birth to our beautiful baby girl a month ago. The first week my husband was AMAZING! He was waking up at night with me when I needed to feed her, he was spending time with her, cuddling her, holding her... basically everything... I was so proud of him and I was extremely happy that my husband was like this... then after the first week everything started going downhill. He works 2 jobs - one job is at a company full time and the other is our family business. He's so focused on his work that he's neglecting our daughter and me. Every time I tell him how I feel he snaps at me and causes a fight. He yells at me so much and swears that our daughter starts crying. I keep telling him to stop but he just keeps going. I feel so trapped. Sometimes after a fight he steps up and then wants to cuddle our daughter but she cries every time he takes her into his arms. It's like she doesn't even know who he is. He literally comes home every day at 5pm to eat and by 6 leaves again and comes home around 10pm... by that time I'm exhausted and LO is sleeping. I don't know what to do. Talking to him is impossible. Every time I try he starts yelling so I started keeping my mouth shut for my daughters sake. We had our share of problems before pregnancy but nothing to extreme... if I knew it was going to be like this I would never get pregnant. But now it's too late. I feel this whole marriage is a big mistake. But I got my biggest blessing out of it so I want to try and fight for it. Sometimes when we fight he mentions how when we go to court he will do everything to get custody because he has a lot more money than me... I need help and I don't know how to help the situation. Clearly he's prepared if we decide to divorce. 😔
