i might be pregnant again..

So I always wanted 3 kids 2 boys 1 girl well i was blessed at 17 with 1 boy and 22 with another boy my second was born march 10th this year... me and my husband had sex 3 weeks after i gave birth we got the ok from the doctor. Since my boys are 5 years apart I would want my next one to be at least a year apart. MY Husband doesnt want anymore kids because all his life he wanted one but we got blessed with 2 so he said no more after this. But..... my husband did the pull out like last time and im 90 percent sure we are pregnant again. And he was drunk AGAIN! so the next day i told him we should get the pill he brushed it off and said to not worry about it he knows he djdnt mess up again.Whatever then... fast foward 2 1/2 weeks hes drinking and were talking he says you really think your pregnant again I told him I think but not sure we habe to wait. He told me please to not have this one or our marriage is over. He sajd 2 is enough and he cant handle it. I immediately got upset and told him we didnt use protection its not my fault you didnt want to get the pill and you know everything.Hes demanding i get an abortion if im pregnant or its done hell file for divorce.Im pissed he did this with our second but only came back because our son needed a sibling. What should i do?
