Probably just checking whether you started to rid your home of things he may have left behind or things from your former M to him that might show that you are just fine with the fact he left and are moving on and getting a life of your own.
Or maybe he is missing you. Really soon for that but it has happened like this with WAS before I am sure.
Just keep DBing and just observe what you see.
My IMC told me to do the same thing and it has helped me stay the course for the most part. Things aren't improving much if at all with my sitch but it is not going backwards either.
Good Luck!! I am rooting for you and your kids!!
