Today was my birthday. No one said Happy Birthday. Not even my girlfriend.

I honestly don't care if others don't wish me a happy birthday, but the fact that my girlfriend did not even acknowledge my birthday cut the deepest. I would assume after dating for 4 years and going out of my way to be the best boyfriend she's ever had that she would learn when my birthday is and at least give me a hug and kiss, but I guess I'm not even worth that. I waited all day to get a text, an invite to her home, her showing up to my home with a cake, her asking how I spent my day or even a hug, a card with heartfelt words, something, anything. My self worth was already feeling bad, but now it's even worse.
