for heaven's sake - he did have a child born via c-section, and like most people was told that if they hadn't been in the hospital and had the c-section that everyone would've died. he's obviously terrified that he could lose you and/or baby, and the way around that is not to tell him he can find somewhere else to sleep if he doesn't like your birth choices. help him understand why it's safe to birth with a midwife, and what risks are involved in hospital births. respect him and his opinion, and help him to understand yours. start taking a birth prep class like Bradley together - hearing those stats from an "expert" even if it's not an MD, and seeing other couples who are on board will help.
give him some time, help him understand. though totally misguided, he does have your safety and baby's at heart. don't forget that.
I came to realize that DH's fear of birth was *his* problem not mine. I had tried to talk to him, show him the research, tell him how I felt. He wouldn't hear it. He could not let go of his fear. I finally knew that it was not my job to fix his problem. It was his issue and he would have to do the work to get over it. I can not *make* someone listen or change their mind if they are not willing to do so. If they are not willing....it is not my job to sacrifice myself to help that person deal with their own hang-ups.
While expecting our 2nd baby I did explain to DH that he was not responsible for me and the baby during the birth. It was not his job to "protect" me from birth. Birth is the woman's work and his only job was to support me. I think that helped him let go of the idea that as a man he is my protector and responsible for my safety.
I compromised the first time and I was burned. It will never happen again. As it turns out I had the best homebirth ever with my 2nd baby. Now, after that birth, DH says homebirth is the best way to go.
