GF and I are currently childless.
I don't suspect this will change too soon, but she wants to, someday, and you know... I think I dread and fear this more than anything else in our relationship. I do *not* want to be "that horrible person who left her GF because she couldn't handle parenthood" or likewise "that horrible person" who "wasted" her time by being with her until then, and leaving her single to ponder parenthood with someone she didn't know as well. She says my concerns are 'stupid' and that I'll 'change my mind' once I hit my mid to late 20s... I'm not so sure. I just know how people tend to look back and say "You knew how you felt in the first place- why are you suddenly bringing this up now?!" when the time to make an actual decision on something comes.
I'm just not into kids... and I wish she weren't either, but I can't change that. She says "Well, who will take care of you when you're old?!" ... I will, and my savings will, or no one will... such is life. I'm not going to have a kid to try to change that.
My nurturing needs tend to go toward my pets and my partner.
It's not that I don't think there's enough love in me to go around, but that if I did have a child someday, I would want to adopt... there are a lot of children out there who need that kind of steady, real love... why make my own?
I'm sorry I have no real words of wisdom or experience to give you, except that family is family and love is love. You and your husband don't love each other less for this, and that's *the* most important thing. You two should focus on being happy together, doing things together, and enjoying your lives together.
