What to do?

My hubby and I have been married for 3 years. I'm not ready for a baby yet. Financially we cannot afford to have a baby right now. I don't think you can ever truly be financially ready, but we're far from it. We both work full time to make ends meet. How would we afford day care? I feel it would be best right now to keep saving and working on our credit. Not to mention I'm not in the best physical shape to have a baby. I'm working hard on it! 20 pounds down! There's so much more risk when you're overweight and pregnant and that scares the hell out of me. Everyday, he asks me if we can have a baby. He won't listen to my opinion, and the reasons we should wait a little longer. He came home from work today and I had on a sexy outfit. He ignored me and said until I'm ready to get pregnant, we won't be having sex. How would you handle this situation?
