My "best friend" for most of my life has been treating me like absolute shit lately, and he has no intention of fixing anything going on between us. He just straight up ignores me, which he's selectively done for months when I try to talk about anything that's going on between us.. Now he's driven his sister to the point where she's wound up in the psych ward, and he seemingly couldn't care less. He hasn't and won't talk to her and he denies any wrong-doing/responsibility when his mother called him out. I thought he was a better man than this, but I'm realizing that he doesn't care about anyone but himself. He's practically torn his family apart in the last couple months and he just DOESN'T CARE.
