Please tell me how can a husband do this to his wife?

I have a son and has always insisted I dont want any more kids. My husband does not have any kids and is always asking me about having his child. he insists we do not use protection or that I dont take birth control. After a brief separation of 2 mths he came back and wanted sex everyday and was quite careless which he has never been before. Now that its confirmed am pregnant every day he says I must go do an abortion and he doesnt want kids with me. I have officially thrown him out and will never take him back. I dont know how to even describe him. A hole is an understatement. What do yo think?
