Also, I agree with putting away the pictures, mementos, etc. You're torturing yourself and stirring up feelings you shouldn't be dealing with right now.

Agreed. I had boxed up every picture of my ex and put them away a long time ago. Yesterday, cleaning up some around the house, came across a few more. You stare at the face in the picture and something deep inside you gets tormented. I added them to the box. Perhaps mark the box, "Do Not Open Until You're 80" or perhaps even, "Do Not Open Ever."
