Yeah, I was empathizing with you heavily about all of your husband’s STUFF you would have had to deal with to get your house ready to sell. This is a huge blessing, him keeping the house.
Who knows, you two might end up as companions in the future. If you can get along during a house improvement project (laying pergo) you have the basis. And I know you are close to your step sons, so those relationships will continue, no doubt.
