Well, turns out things are a lot more complicated than I thought. He's said a lot of stuff about people not caring about him, only doing stuff because it benefits them or has the smallest burden on them (which in fairness he has a point), actions speaking louder than words, etc. And well, I love this guy and seeing him in so much pain honestly breaks my heart. I've done my best to try and show I care, getting him get well soon cards and stuff like that (he was in hospital a lot recently) and trying to check in when I've thought he was upset (also has a fair amount of mental health problems) but there's only so much I can do without being weird, so I don't really know what to do to try and support him. Other than sending him a link to this site but that's probably not a good idea.
Hell, part of me is hoping that he's just bullshitting this to me because he actually wants nothing to do with me and that he's actually out there living his best life and is having a great time. I don't really know anymore though.
