Help please

Hi, I’m 12 weeks with mine and my husband’s first baby. He’s never been financially stable and I have okay but not great. I’ve always earned more and previously he earned around half. However in April, he stopped getting an income at all and said he was focusing on his own business. Not having any income has made us very financially strained. I’ve asked him to get a job multiple times and he hasn’t, instead he sold his car and uses mine. Our bills alone come to £3k a month and previously he would send me £1.3k and I’d pay for everything else on-top of bills. This month, 2 weeks after he owed me the money, he sent me £150 and said that’s all he had (No prewarning). I’m really angry as I don’t have a spare £1.5k so using all the baby savings I’m trying to clear our bills and I don’t even want to get started on mat leave. What do I do?
