I don't understand

She likes you, she loves you
She wants you, she has you
She breaks you, she hates you
Then she dumps you....
Yet you try to get her back even when I'm the one who loves you you and wants you and would never dream of hurting you.
I would always be by your side but you still don't understand, why don't you get it? It hurts to know I'm not good enough...even when I'm your girlfriend! Whats it gonna take for you to understand that I LOVE YOU! Do you even realize how much pain your putting me through? You tell me you care but deep down I know you don't care. But whatever....do what you want, cuz I'm done...
