Had anyone been in my shoes?

I just got married last year. I have no bio kids of my own, while my husband has (1) 11yr D. My hubby loves kids, but ever since he got custody of his D, he doesn't seem as eager to have any more kids. Which sucks for me considering i'm 30 with no kids! the clock is a-ticking. He wants me to be more of a mother to his D. But that bothers me because she has a mother who is still very much in her life. And because i think he hopes that me getting closer to his D will satisfy my want to have my own kid. (which is just stupid). What do i do?

And....what if we do have a kid? It will be my first. I'll be soooooo excited. But will he be? He already has a kid who he loves more than life. No little girl grows up dreaming of being the 2nd wife. I wanted the thrill of having a baby to be something we share. Not something that i'm happy about and he's bored with.
