you&i both

There are reasons why we're not together. 
It is laid neither only in you nor only in me. 
It is laid in both of us. 

Two words "thank you" must be said.
Not for coming, but for going away.
Not for your courage to stay, but for your courage to leave.
Not for your perseverance to work on relationship, but for your perseverance to end it.

thank you...
