Hi Chris,
I'm sorry you're going through this. One thing that worked for me was to concentrate on taking the place BACK. My ex took his OW to a few places that were "ours" - NOT a home (thank goodness), just restaurants, stores, etc. I had to sort of exorcise the ghost of her by going back to the places and making an effort to get NEW memories.
Maybe you could help your son re-decorate or just move furniture around, anything to change it just enough to make you feel like it's YOURS again.
Enjoy the FL weather, see the sites, do new things to re-create new memories. Have some key lime pie for me, nowhere on earth makes it better than Florida.

Monica
My yesterdays are all boxed up - and neatly put away.
