Oh L., I know how painful this is. I have been there myself. My story works out in my favor. My husband was just as excited as I was when we learned we were having our 3rd child. And my conscience was clear because I know that I did nothing to manipulate the situation.
Think about how you would feel if your husband betrayed you that way. That's not what you want anyway, is it? No, you want him to want another child just as much as you do.
Share with him your heart one day when you can do so without being angry at his response. Don't try to manipulate with words. Just simply share with him how you feel. Then allow him to do the same if he will. My husband shared with me how sacred he was that he wouldn't be able to provide for us all. Our husbands need to know that we love them unconditionally. With or without children even when we want them so badly.
I believe in the power of prayer too. Ask God to open his heart to you. I know that whether you have 1 child or 100 children, your first priority has to be in loving your husband no matter what.
Try to focus on what you want in a positive way and of course be so very grateful for what you already have. In fact, I am making a list of at least 100 things that I am most grateful for in my life. This helps us to change our focus from what we don't have to what we do have. And remember, life is all about the journey not the getting to the end so fast.
