Thanks everyone. The surgery went well, the surgeon was very optimistic that the surgery should do some good things for my legs, and they discharged me a day early.
Ok, I need to share a weird story about W. W and I are separated for over 2 years. And after the surgery the doctor wanted to make sure I was staying with someone for a week. I had arranged to stay with my parents,
W attended the surgery and when the surgery was over, she came up to me (and I was chock full of pain killers and other drugs) and said that for the recovery I could stay with her and the 2 youngest kids at her place (?!)
I declined her offer, saying I was staying at my parent's place. It was a nice offer that came totally out-of-the-blue. But don't think this is progress. When she posted it on FB, she referred to me as "ex-husband".
