Yeah if he isn’t ready for children yet then I would say he won’t ever be.Just think about the children, they won’t want to be in their 20’s just starting life with 2 geezer parents who are too old and tired to enjoy life with them or see their grand children... you don’t live forever, I have 3 children with my wife, one with my ex, and one with another ex. No disabilities or rare disease at all. All healthy and normal actually the 3 we have are in top percentiles, because my wife is a teacher and works around the clock to makes sure they are well rounded, with the help of me of course. Idk you just have to do what you want with your life and keep pushing. Find your way to success.
