To rather DP didn't "treat" me to anything at all?

[lindter]

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?

So does he use his good deeds as a get-out-of-jail cards in arguments? Or just bring them up generally? If it's the former, he sees your relationship as transactional where he can buy favours/compliance/good mood/sex(?) from you with his actions. If it's the latter, he probably just feels undervalued and is possibly genuinely trying to be nice. I'd have a serious talk about this before going forward because you'll quickly exhaust any interest in life together if he thinks you're a vending machine.
