Then stop. I know it will drive you crazy but ONLY clean up after yourself. Let him sit in his own filth and if he NEVER shows any motivation to not live like that? Just pack your shit and leave him in his own filth.

This is plain disregard. Don't let anyone tell you this is executive dysfunction cause it's not. I have executive dysfunction and the guilt eats me alive every single day, especially on days I don't get a single chore done.

Tell him that there is a difference between unwinding and escaping reality and he is not living in reality at the moment. The reality is that he is an adult and he has responsibilities beyond work.

Unwinding is fine IN MODERATION. Sometimes I get stuck on my PC games too, but I work myself around "one more round and I'll get up and do a load of laundry and then start another round." Because my executive dysfunction might be trying to drain me, but I can fake it out with intermittent dopamine inputs.

He doesn't even seem to think keeping any part of the house clean is something he should DO, He's not struggling with this at all. He just wants you to leave him alone so he can game in peace and you can clean up after him like his mommy. You should send him back.

LMFAO she put it behind it and everything. Maybe she's really naive and thinks it's just a pretty flower.

You're single now, dude. She's not your girlfriend anymore. So I guess you fucked yourself instead.
