I cried a bit. :(

I have a genetic issue (recessive for me because I'm female) that causes 50% of boys in my family to be born with Becker Muscular Dystrophy.
I'm having a boy, but I do not know if he has it yet. I didn't want invasive testing to test it. I will be getting his bloodwork done when born.
I'm a FTM. I also want a couple more kids in the future but my husband WILL NOT budge. He says that he doesn't want to bring a child into the world with pain, which is nice, but not every boy has it and females are carriers! So it's only a 25% chance. I have two brothers with it, but they are very happy and say that it doesn't really disrupt anything, except joining the military or doing intense sports.
Is it fair for my husband to be this way? It broke my heart that I will not have the family I hoped for, with siblings. I can't help but feel selfish... It made me cry. :(
