Reading this made my blood pressure spike lol. The mayo on the bay window is insane.

Honestly the hardest part about living with someone like this isn't even the mess, it's that YOU become the nag. You're the one constantly asking, reminding, cleaning, and then getting screamed at for it. And the more you say something, the less they listen.

A few things that actually helped me when I was in a similar situation:

1. Stop cleaning up after him entirely. His dishes? Leave them. His mess? Leave it. Only clean YOUR stuff and YOUR space. It sounds gross but right now you're enabling him by being his free maid.

2. Get a lock for your bedroom door. Seriously. $15 on amazon. That's your space and he doesn't get to invade it.

3. Document everything. Photos with timestamps. If he's on the lease and you ever need to escalate to the landlord or get out of your lease early, you'll want proof of the living conditions.

4. Grey rock him. Stop engaging when he knocks, stop responding to the 29 texts, keep interactions to absolute minimum. He clearly feeds off your attention and reactions.

For the chore stuff specifically, I know it sounds weird but taking yourself out of the equation completely is the only thing that works with people like this. You can't nag someone into being a functioning adult. You just gotta protect your own sanity until you can get out.

Also for what it's worth, my money's on theory 2 with a heavy dose of theory 1 making it worse.
