The flip side is he blows his public assistance check on dope instead of paying his rent. He refuses social services and medical care. And instead, demands you give him money, bring him food, do hs laundry and clean his filthy place to the point that your own ability to work and your health is compromized.
Your misery/agony and exhaustion with this situation is palatable to even the most casual reader.
If you want to continue putting him before your own needs, that's your business. If so, can you take joy in any of it?
