I get where Glamgirl is coming from. Through her consistency in the way she treated her H he finally realized that if she was really done with the R what he would be missing. Sometimes we really don't seem to know what we have until it's gone.
I say go for it. As you say what do you have to lose? Your XH may go quiet as he tries to process his feelings. At some point he may also realize he wouldn't want to lose you from his life forever.
Tell him when you set up the next TT session that you were sore after the last time and you wondered if you could come and soak in the hot tub afterward. What the heck, it's worth a shot.
Just remember not to take anything personally, it's going to take time for him to process it all.
