You guys JUST got married. Maybe he wants to take some time to enjoy your marriage or at least make sure its stable enough to bring a child into the world? Having a child is not just about money. I don't think it's something to want to FORCE on him if he doesn't feel he is ready for it, which is doesn't sound like he is......right NOW. That doesn't mean he doesn't want kids at some point. Forcing these sorts of very big decisions in a relationship can lead to resentment and breakdown of the marriage later on. Build your marriage FIRST. This takes time.
It almost seems to me like having children is more important to you than your marriage. Don't you want to spend a few years enjoying your time with your husband? Honestly, I adore mine and I love it being just the two of us. I'm not yet ready to shift my attention away from him and onto a child because they DO become your centre of focus once they come around. You're so young. I know it's important to you to have kids, but you have soooo much time yet, honestly.
