I think I did pretty good with the NRT, though you will have to check out my thread to see if I am booted from the NRT support group (at least I didn't initiate).
Sounds like you did pretty well. Good job on avoiding the fight over the phone use as well. I have had to bite my tongue a few times that I normally wouldn't. I usually follow it up with something like "its all good" meaning life is good this is no big deal if we start to lash tongues.
I think making these last few days very pleasant is a good approach....show him what he will be missing before he misses it.
PS: You are not evil to want him to miss you.....you are worth missing
