This past year I have become increasingly resentful towards DP for many reasons. We had a falling out recently which has resulted in me losing all respect for him. Since then I've tried to just keep things light so the atmosphere isn't as horrific as it was but he is acting like everything is A-OK. It isn't in my mind. He keeps going on about how I have said no to getting Christmas presents. Am I being an arsehole for not just buying him a something?
