I think he just loved being with the bears because they didn't make him feel bad. I get it too. When he was with the bears, they didn't care that he was kind of weird, or that he'd gotten into trouble for drinking too much and using drugs(which apparently he did a lot of). They didn't ask him a bunch of stupid questions about how he felt, or why he did what he did. They just let him be who he was.
