Your situation sounds very much like mine. I'm sorry you're going through this. The only thing I can say is keep focused on YOU - your pregnancy, the baby, the preparations, and just leave him out of things for now. It doesn't seem there's anything you can do anyway. He has to come around. It's like ignoring a toddler who has a tantrum while also giving them the love, safety, and support they need. Have you read Laura Munson's book (I just found out about it - oh, but it didn't come out yet - shoot.)

Have faith.

BTW, I'm wondering if there's anything in your relationship that he could be resenting/upset about/etc. prior to the pregnancy.
