Opinion on this abortion?

Me and my boyfriend may both be Carries  for cystic fibrosis and he says that he dunno what we should do if we find out that our baby has cystic fibrosis... He said it's not nice his little cousin has it and there in pain. People with cystic fibrosis die early you don't want to see your baby die before you? It's not a quality of life.. What do you do in these situation personally? What do you think is best to do? I don't know if I'd ever forgive myself..
