My Friend, My Foe

I have a Friend,
I have a Foe.
I fight with my Friend.
I bond with my Foe.
My Friend left me,
My Foe stays.
I hate my Friend,
I miss my Foe.
My Friend pulls me down,
I praise my Foe.
I call my Friend Goodbye,
I named my Foe best friend.
My Friend destroys me,
My Foe fixed me.
My Friend is a jinx,
I wish for a Foe.
I love them both,
I ate my word.
