"Remember most WAWs (not sure about WAHs) have been plotting their escape for two years prior to BD."
I've been thinking that my W might have been doing so on/off for 2 years. 2 years ago to the month her parents bought a house locally and left it empty since then. My Mum has been saying she thinks they bought it so that W could move into it any-time she wants. I recently found out that they had put it up for sale again last year when W & I had a great holiday but then took it off the market again soon after. They were decorating the empty house in the months before W left me, and W had been taking things to the house to store there and taking cash to hide in advance of D.
