I think you did an awesome job. I do not know how many people could have pulled that off as nicely as you did.
Personally, I ALWAYS love hearing stories like this. It is great to hear of how people have "moved on" without their spouse who blazed off in one way or another. I agree with the old saying, "Living life to the fullest is the best revenge." I think you showing up, acting as you did and having another man in your life speaks volumes to your exH.
