How did you deal with a partner not wanting kids?

My boyfriend and I are both young, me being almost 20 and him being 19. I know that in the future, I would most likely want kids. He has told me he is unsure, but at the same time he often talks about what he would do if he was a dad.

I think for most men they take a long time to decide if they want kids. Our relationship is so great, and I could not see myself without him. I am just nervous that one day he may decide he doesn't want kids and I will.

Have you had a partner who didn't want kids when you did, and what did you do?
