Am I overreacting?

My boyfriend of 3 years has become grumpier... it’s small things too but when we talk about how he treats me he says I’m the one overreacting. Am I? When he is rude and I correct him am I? I’m in bed upset and he out in the living without a care in the world. My parents would be heart broken if they knew how sad I was. I’m 19. Advice??
