A lot of men resist having more children then are thrilled when it happens. BUT, it's not worth risking your marriage. I begged for my last 2 children. Things were fine when we had # 3. But when he finally decided we could try for # 4 he really wasn't ready and was only telling me he was because our marriage was on the rocks for other reasons. He felt that he would do that for me and that would make it all better. But then he resented me the whole pregnancy and said a lot of mean things about how our finances would be and how he didn't really want more kids. He was always saying derogatory things about how old we would be when the last one was finally gone. He even insinuated many times that there was something wrong with me the way I felt like I needed to keep popping out babies. I would have gladly had 3 or 4 more. But it was very painful hearing those comments all the time. I almost left him over that! He even said some things after she was born and I was always afraid that she would hear and get a complex. She's only 7 though and it's been a few years since he said anything particularly bad. He loves her like crazy and she really loves her daddy. But I'd never push it again.
Whatever you do, if you value your marriage, don't push things too far. Just talk to him about his reasons. If it's money then you can do something on your own to make things better. I see you are a stay at home mom and you move a lot. That puts quite a bit of stress on the family and changes the types of houses you need to live in. Men are really worriers about money. But if it is only money that's bothering him maybe you can find a way to bring in extra money and put some savings away before too much time passes and then revisit the conversation when he's feeling better about things.
