I think there's a little voice telling you to bow out of this invitation. Heed it. Although curiosity might get the better of you, if you felt any twangs of emotion when he suggested this meeting, it probably means he still occupies a large space of your heart/mind. It might be better if you decline, and when it gets closer to selling the house, then get together to conduct business. If this IS about his regret, misc., he will somehow continue to keep contacting you.
I do think it is a very wise decision not to put the house on the market until after the holidays. People really don't seem to go househunting that time of the year anyway.
If you decide to decline the invite, just do it in a straightforward, friendly way. If he is sticking his head out a little bit, no use knocking it clear off by being too cold or indifferent. LOL
Women are angels. And when someone breaks our wings, we simply continue to fly...on a broomstick. We are flexible
