Husband doesn’t want the baby

Have had an accident and ended up pregnant. We have had 4 miscarriages and have 2 lovely children. My husband is 51 and says that he can not contemplate going through it all again. He says he will never be able to retire and that when he will be 63 when they go to secondary school. I just don’t know what to think. It is not an ideal situation (neither of us would have chosen this) but I can’t get over the struggle we went through to get our other children. We have a hospital appointment tomorrow to discuss abortion but I feel terrible about it.
