How so I respond to this!?!

After 8 years together, my husband admitted to me tonight that his reservations about having kids is that he doesn't want to lose me as a wife when I become a mother...

I am a micro-manager and have a somewhat obsessive personality. And he's afraid that if/when we have kids that it will consume my whole world and I'll stop being the wife he fell in love with and instead only be the mother of our children.

How do I respond to this? He's absolutely right about my personality, but I have every intention of still being the woman he married and becoming a mother as well. Basically his point of view boils down to this: having kids will result in the end of our happy marriage. Either we'll fight too much and get a divorce or just stay together and end up hating each other.

I feel completely blindsided by these statements and hurt that he doesn't think I can be both a wife and a mother. How do I make him understand how much these statements hurt me and convince him they're unfounded?
