I have been in the same situation. We have 2, but I wanted a 3rd. (My DH doesn't want another because he's afraid we would be too overwhelmed.) When I was actively in labor with our 1st, it was quite painful and there were a few minor complications. It wasn't huge, but it scared him. He also felt awful/helpless to see me in such pain. We had a 2nd after we talked at length about another being worth the pain.
If your husband remembers the pain that you felt after your miscarriages, it is understandable that he doesn't want either of you to go through it, again. You need to see if there are any more reasons from his viewpoint. Then, you need to tell him how strongly you feel about having another baby. Perhaps, then, he will see that it is worth the pain to you. I don't think that his not wanting more kids would constitute divorce, but it can obviously lead to resentment, then divorce. I hope it works out for you.
