Husband said I don’t have shit

Last night I mentioned to my husband that our girls needed a bath and he agreed they did. I was working on schoolwork (I’m in law school) and he is on vacation from work so he was just lounging around all night. I fell asleep in the home office and when I woke up the girls hadn’t had a bath. He said he refuses to give them a bath at night because he doesn’t like to prepare for the next day and would give them a shower before school. They’re twins but one has sensory processing difficulties and hates to shower in the morning and it absolutely traumatizes her and ruins her day. Every time we give her a shower in the morning she has a bad day behaviorally; she’s also nonverbal and she expresses her discomfort by screaming. I told him I didn’t think she should get a shower before school and we could do it tonight. He says that he isn’t giving her a bath at night and that I could do it because he doesn’t want to do anything that he doesn’t want to do. I told him that isn’t fair because I don’t get to just refuse things I don’t want to do and because it’s to accommodate our daughter. To which he suggested we separate or I move out to which he says “but you can’t because you refuse to live with your mom and you don’t have shit”. I don’t know what to do. This is the second time this week he’s not done something simply because he didn’t want to. The first time I missed a tanning appointment because he decided he didn’t want to pick the girls up from school and he told me to go but when I got there he’d already picked them up and I lost $50 deposit on the service plus the $25 cancellation fee. I don’t know what to do and I’m fed up.
