I have never been married. nor am I a parent. And this was a conscious decision on my part. There are many wonderful things to fill ones life with...art, music, travel charity....life.

This said, his decision to not have children whatever the reason may not be just a passing fancy, and should be respected & taken seriously. Sounds like you are both simply striving to find your place in the world. You will need to decide what is important to you. Not wanting children is just as valid a choice as wanting them....In my experience, we rarely end up with the one we loved the longest or the one we loved the most, usually its all about timing. You both deserve to have the life you want, and that life can only be lived together if you are on the same page.
