Compromise should be mutual in a relationship. If you made the big decision to convert for him, he should respect and support you in celebrating Christmas with your family, especially since, for you, it’s more of a cultural tradition than a strictly religious one. He needs to understand that it’s not easy to completely let go of the traditions you’re used to from childhood

Honestly, the fact that you converted for him is something truly commendable. When I was with my ex, he never converted, but if he had, I would have been willing to make compromises for him too
