I may be wrong, but he's gone MIA because he knows that you want to have an adult discussion about the taxes and the sale of the home, as well as any other things related to a separation/divorce. He's going to "hide" until he thinks that you aren't focusing on a separation/divorce and the sale of the house. They do this quite often. He thinks, out of sight, out of mind and they bury their heads in the sand when it comes to doing what needs to be done.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
