I use to adore you

Bitterness becomes a friend to the one who was a friend,
I learn to not care for the one who doesn't care,
It grows like a pest but reveals the truth,
A two sided coin that hasn't been flipped for a while,
Yet I stood like a begging child,
Anger and resentment grows,
It never ends, it keeps going till there is no more miles,
All I have to do is wonder if you are still worth while.
