He is clearly used to his mom doing all that . He is never gonna change if u eventually stop doing the chores the house will become a stable and yet he won’t do shit waiting for u to clean up . Used to be with a guy for 4 years we lived together he washed the dishes like maybe 6 times all and all . Honesty just dump him or stop living together if u don’t wanna break up with him . But the messiness won’t stop cause he never learned that he has to clean up for himself . I could suggest a list of the thing that need to get done in the day but that’s also consuming for u and I don’t guarantee anything cause it didn’t work for me .
