Co parenting

I'm a single mother/parent my child's father seems like he doesn't want to be a father, he never came to the hospital to see our baby boy not once but claim he was on the way for days, it hurts me because I don't want me son to grow up without a father thinking he's the one who something wrong or even I did something wrong, I never asked my ex for any money just to get certain items and he never did, we use to be best friends it's not like I'm some random female he got pregnant we stayed together, I blocked his number the other day after he didn't show to the hospital once again, I don't I should keep him blocked  or keep giving him chances, I understand being scared but how can you miss the birth of your son I'm just beyond hurt by this situation
