Ahoy- Moving ain't fun. I am having painful sense memories remembering all the sneezing fits I had clearing out of the last house. Hugs to you!
I know you don't want to deal with STBX (I tend to be this way) but I also agree with Maybell. I assume you guys are splitting the proceeds of the house? Then he should compensate you in some way for all the work you are doing (keep a log of all the hours).
