Been there done that......my DH retired and for two years we did the same thing. I was still working and he left to work on our "new" house every week and came home on the weekends. I loved my job but it was still very hard to be alone all week and just see him on the weekends.
Now, I have retired and we have moved. (new house still isn't completely done but we are living in it!!!!) And, I hate to say this, but our old house still is there. The housing market is so depressed in our area, we will probably rent it until it recovers. (like when is that going to happen....)
Hang in there!--Sending big hugs--keep busy and I hope the house sells soon :lol:
