Because

It isn't because you pawned my most valued possessions
That I don't buy you anything to call your own

 

It isn't because you binged on alcohol when I was sick
That I never call you a doctor

 

It isn't because you left me in the desert alone
That you don't get the car keys

 

It isn't because you abandoned our dogs
That I don't allow you any pets

 

It isn't because you messed with other women
That I chase off all of your friends

 

It isn't because NOW you finally love me
It's because I DON'T LOVE YOU anymore.
