Husband kicked out my mom

My mom has been taking care of my kids since they were born. We both WFH. She recently told him to hold my four month old daughter better and he got so pissed he said she has to go. She comes Monday through Friday and sleeps in our basement. He told me I have to choose between him or her. I said that’s so unfair, she’s trying to help. She takes no money and she watches both my kids when we work. He’s been controlling a long time and that just made me feel really hurt. I have a 18 month old son who loves her. Anyways I told my mom I want a divorce and she said why I said because he fights me for little things and it’s overwhelming and I told her about that incident she started to cry and said she knows he hates her being here so she will leave now she takes a taxi to and from early in the morning to come. That he pays for. Over 100 dollars a day. I’m planning on going through with the divorce, he’s saying I’m unreasonable. He really is jealous of my mom and I relationship. Saying why do I eat her food and he wants to cook for me instead. Am I crazy???v
