What should I do my boyfriend mean to me because I accused him cheating?

We had a big argument and I thought we already solved the problems and forgive each others but today he's so mean and said "that's my expression of love" in joking way but I feel like he holds a grudge and he said "lets make a deal if you stop accused me cheating I will stop being so mean and I still love you" I feel uncomfortable so we have argument again and asked what should I do? He said "don't be so dramatic" don't know what to do
