The dreaded me is back again. I hate to beat the dead horse again, and I could be beating the wrong one, but I have to come back and revisit the ex-wife thing.
It seems to me that your wife, in addition to her desire to live 'out', has a need for distance. Distance between you and your ex.
Some of the things you have written intimate that your ex plays a more prominent role in your current relationship than it should. If it is even a little too much for you, it could be a 100,000,000 candle power spotlight to your wife.
The trip to look at properties would be an attempt recognize her need for distance and prove it.
As I mentioned in a post way back when, the relationship with your ex, forced as it may be, is a sore point with your wife.
Since this is her first marriage, she has no other point of reference for dealing with ex-spouses. She is depending on you for those boundaries, and I suspect she might be very uncomfortable with the ones you have established.
That's all :-)
