Teenage Stepson chores and cleanliness

C: My stepson has a dirty room
T: My husband should be enforcing chores
F: Annoyed
A: Tell my husband that his son should be cleaning his room and it’s up to him to enforce it.

R: husband shuts down and we fight. Nothing has changed in years.

I’m trying to get to a place where I can feel better around my stepson not having chores. He is 15 and the only thing he does around the house is dishes. I feel like he should be helping out more. My husband says he doesn’t want to yell at him every day to do his chores and therefore just lets him do what he wants.

I’m having a hard time trying to find a bridge thought that will make me feel better. I understand where my husband is coming from but I also can’t stand the mess.
