Okay thanks. Hope you don't mind me asking more questions so we know a little more how to help.
Did you read the posts made by your S while here on the board?
Had you threaten to leave or tell S you wanted a D?
I know you had been thinking it over several months, but was there something that was the deciding factor for you? Did it increase your desire to work on the M when you saw S stepping away from you....or you thought you had waited too long to show interest?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
