You'll be tempted to (you'll need to) talk to others.
They'll be tempted to ratify what has happened.

They'll tell you what was wrong, what was not worth loving.
They'll remind you of all the bad times--ignore them.

Take this time to do what seems the least natural: 
Make sacred the things that always were (are) sacred.

Curate & cherish what it was like to love her.
You'll have nothing but time for anger if you choose. 

Choose instead memories that water your dry heart.
