DH does not do any cleaning housework (20+ years living together). He has occasionally offered, and I would always say no it's OK, as he doesn't know how to do any jobs, doesn't know where the cleaning stuff is kept etc. and asks so many questions it takes up more of my time than doing it myself. But it's gradually been dawning on me that I am enabling him to be a lazy arse, so I made up my mind that the next time he offered I'd say yes. After some months he comes up to me while cooking and says is there anything he can do? So I say yes can you wipe down the downstairs loo. Instructions & products given, loo cleaned, then I hear the front door slam & he disappears for 2 hours, and silent treatment when he returns. Turns out he was actually offering to help with cooking. AIBU to think he behaved like a childish tw*t?
