We are about to relocate to a place nearer to were I work. When my wife told her friend (let's call her Anna) she started to act quite weird.
First Anna started to complain about the town where we are moving. Then she reduced communications with my wife, i.e. they were calling each other every day but now it is much less often and Anna cuts the conversations short.
We don't live near her and the new place would be the same distance, so it's not that she's sad we are moving too far.
She suggested we move to her town, but it's too far away from work and very expensive (for the same price we'd get a 2 bed house instead of a 4 bed). She admitted straight away we couldn't afford a house there.
My wife pointed out Anna wanted a house similar to the one we are buying, but I would be surprised if it was just envy.
How can we approach Anna to ask what has caused this change?
