Yikes, Praying, I'm feeling echoes of the struggle of getting my XAH out of my place too....hugs to you, been there, know how you feel.
In the end, even tho it wasn't "my responsibility", I gave up on trying to force him to get the rest of his crap out of the house and just took up my mighty wheelbarrow and moved it out to my brother's shed myself. The satisfaction of having it gone was worth the resentment of "I shouldn't have to do this", and I'm guessing this is somewhat like your Piano Situation. Sometimes there is a tradeoff, I think...
This thread runs to 3 pages, but if you have time, you might like to read it--you may see some reflections of your own current struggle as well as some great advice and support from the SR Crew:
