Dear Thelma: I'm abused by my girlfriend and walking on eggshells

Dear Thelma,

My heart is broken. We've been together for four years but I feel like I'm walking on eggshells – she gets angry over some of my "mistakes", and things can get ugly when things do not go her way.

She says things that hurt my feelings, like calling me an idiot, saying I have no heart, am a dull person, or saying she hates me or I'm an eyesore for making those "mistakes".
