[Fallout 4]Why is it so hard to convince Paladin Brandis to return?

I get that he's traumatized, but how is staying trapped in a cave going to help?  Why not go back to a place where he can have human contact, medical care, and basic quality of life?  It would make sense if he had built a life for himself in a peaceful farming town or something, but it seems like he's choosing to stay in a horrible situation for no reason.

His pride kept him from going back. Losing his squad, then the years spent alone convinced him that he was no longer worthy of being a part of the Brotherhood. And the longer he was away from his brothers and sisters, the more he convinced himself that he wouldn't be welcomed back even if he tried. Excuses like being too old, too weak, too cowardly. He even had a growing paranoia that he would be seen as a deserter if he went back. Basically, he came up with every possible reason to never go back. And thus, it was extremely difficult for the sole survivor to convince him otherwise in a single conversation.
