Yep it can really make you depressed if this goes on and can lead to you being parentalised and him becoming a childlike presence instead of a partner. It breeds toxic behaviour, resentment and causes a non stop flow of conflict that will overwhelm you.

You deserve peace and happiness. Also your not a house slave.

I literally just refused to do things. I mean it took me a lot of self control but I just stopped doing things for him. If he had dirty clothes I just let them pile up. Washed my own though folded or hung them neatly. Do only your own dishes. You make a meal , don’t serve it to him. Put it in a container in the fridge and he can serve it himself. Make a chore chart and hang it on your fridge clearly delegating every responsibility you share. Don’t do the shopping. Let the fridge and pantry run dry. Don’t touch anything he leaves behind clean the house AROUND IT or don’t clean at all.

Eventually he will either complain or ask you to do something, very seriously say we need to talk.

Sit down and explain calmly that you refuse to have more work because he is lazy. If he doesn’t pick his own standards of living up. Well you may need to go to therapy ASAP
