Husband doesn't want babies :(

After being with my husband for 10 years, he doesn't show any interest in having babies. Initially we didn't think about family for a few yrs but now I am almost 30 and I really want to have babies. For 2 years I have tried talking to husband about why he doesn't want and all he says is we will have them someday. He doesn't show interest in learning about my ovulation cycle or anything baby related. Meanwhile, I cry all day. Feel like I lost a baby I never had. Anyone else going through a situation like this? ( I hope not)
