Can I make myself want a baby?

Husband is desperate for one & I just don't get it. I like kids, but I don't want to grow one. I would probably be a good mom, but I don't want to give up my freedom, flexibility, or money. I felt similarly about pets, but now I'm crazy for my two cats.

I want to give my husband what he wants, but a baby is a life changer.

This is my fault. When we met, I told him I wanted a family. Now I don't want children.

Help.
