I had the problem with my companion too, and was able to solve it over time (a LONG time), so here are my two cents, I hope it can help. Of course, I did the "good honest talk" with him exposing the problems and stress that came with hishim postponing his chores, and that almost always. Each time, he did see my point, agree, and actually made a lot of effortseffort... for about a week before falling back ininto his previous behavior. So I had to go more practical. Two approaches proved to be successful
First step: adapt the distribution of chores to this problem.
Example: we went from a "I cook, he doesyou do the dishes" system, where I would end up with an absolutely hideous kitchen and him asking me:"Which "Which items do you need me to clean to cook tonight?" to a "I do everything for the meal including cleaning afterwards, and when the kitchen is clean, it's your turn". It was both positive reinforcement (cleaningclean everything one good time after eating -> You you get to do nothing for the next (few) meal(s)) and negative reinforcement (postponingpostpone cleaning -> you get to cook again AND still clean for both meals) Plus, if one doesn't do his part one time, it's not getting in the way of the other.
secondSecond step: support each other
ProblemThe problem with the first part is itswas that it's quite strict ruling. We did it in order to get us a bit straightened, but once he was more used to actually doing chores regularly we ditched it (part of the initial problem was that he had almost never had to help at home, so it didn't register to him that there are chores to do EVERY DAYSDAY, and not just when you feel like it) we ditched it. Instead I began simply asking him to help with something while I doing something else. Example:
Would you mind folding the dry laundryclothes while I hang the wet oneones?
or
Could you please help me and empty the dishwasher while I clean the floor?
Key-point: It's simply motivating not to be the only one doing chores, and the feeling isyou both get a nicer feeling when everything is niceneat and weyou did it together. (and it's difficult to turn down something like that without sounding quite rude) It. This also got him to get out of the "I have to do this because we ruleruled it like that" mindset, to get into the "There are things which need to be done there, and I can as well do it as well, even if it's not explicitly on my list". When When he began to dodoing chores by himself, I would then always do something as well, and now he does that for me too, most of the time.
