The key to a successful and happy marriage is to be open and honest about how you feel regarding major relationship points, such as the concept of having (or not having) kids. I feel that if you aren't fully committed to the idea of being a mother, than it's best not to have them just to please the H. You'll grow resentful and the child or children will not have a fully committed mother and that's not fair to them.

So, talk to your husband. He married you for you, not because you have the ability to bare him children.
