This is horrible! She was so disrespectful of you! And while I'm sure you love your hubby deeply, he was (IMHO) out of line as well. You're not a child; you don't need someone to speak for you. I can see how he might have meant no harm, but you must have felt ganged up on by the two of them. I'm glad that you had this forum, and knew that there was support and advice waiting for you once the pain was under control. Without that, I think it would be a lot harder to maintain the positive outlook that you do.
My PT(assistant) told me yesterday that we weren't at the point where he (probably 250#) would have to sit on my leg with it supported top and bottom to get the extension I needed, but that might be a possibility down the line. And I looked at him and didn't say it out loud, but thought, "You would be so fired if you tried that."
I hope that you are able to have a restful, pain-free night and a better tomorrow.
