DP and I don't live together, no children together.
He earns more than I do. He says a lot that he loves being able to "treat" me.
Every time he pays for something, or does something for me e.g. gives my house a tidy whilst I'm out, he has to bring it back up.
Either in an unrelated argument he'll say "I paid for x earlier!" or "I cleaned your house for you, because I want to make you feel good!"
Or, he'll bring it up jokingly. But he HAS to bring it up. When I call him out on this, he finds it offensive.
AIBU to refuse next time he offers to pay or do something for me?
