I think the thing that doesn't jive for me with J/H most of the time is that theres a lot of stuff where its made out like jean is ooooghghg Suffering because harry doesn't Care for him as much as he Cares for Harry and it rings really false to me. Harry would... care a lot? He would care very very much and in his own broken way try his best to express it? Maybe it wouldn't always come out right (see: the video game disco Elysium) but he wouldn't Not Care As Much. He would care. He would care so much it would be a major source of tension in whatever they'd call that whole situation, because (points at jean) unable to reciprocate even if he wanted to, which most of the time I doubt he does.
