Time to move on. Since you’ve never been to his home, never met his parents, he never spent a night with you or travelled anywhere, whatever he says is all hearsay. If he wanted help, he’d ask for it over many years you’ve know him. Since you officially broke up, trying to contact him is not healthy. Since you aren’t in a romantic relationship, he’s not obligated to contact you and is free to pursue other relationships or not.. Let him live his life

There are ton of people who do need help and would welcome it. He chooses his way to live. He refused to have normal relationship even before his parents got sick and old. It’s a choice.

Many people need help because they don’t have a choice: sick, disabled, young children, elderly etc If you are inclined to help people there are ton of people/kids/animals you could help. This man isn’t one of them. He’s not interested. He is a grown up.

Please don’t waste your life on men who aren’t interested. If you truly just doing it because you just want to help, then there ton of people you could help.
