What to do when you want a baby and he doesn’t right now

Me personally I want a baby really bad and think about it every day and talk about it a lot with him he on the other hand does want kids but isn’t ready for it and tells me no which I respect that but how do I get over myself for now? I want it so bad I have dreams about it I get jealous when my co workers got pregnant and it also hits hard because I had a miscarriage at 6 and a half weeks over a year ago and it hurts me to think I could’ve had the baby if my body didn’t betray me that it would’ve been a reality I would’ve had my baby I always wanted but I don’t know how to just let it go for now or why I’m so attached to the idea any suggestions or comments are really appreciated
