Decisions

I've been dating a guy for 6 years, been pregnant but the timing was wrong. I'm 36 and don't want to wait any longer to have kids, we have talked about kids in the past but due to his past BM he has a wall up about having more kids, would I be wrong to ask for that as a birthday present along with facts of why I deserve the most precious gift? If he says no I have decided to no longer sacrifice my happy for his, is that selfish of me? He always tells me to be patience but I feel like he is pulling me alone hoping I just quit the baby talk.(Side note we have knew each other since I was 19) so our relationship runs deep.
