jlh, don't worry about it. Give him the time and space to work out his own stuff.
Personally, I am a big fan of the of "I am letting you go" discussion with WASs/WSs. I know that my saying that to my W had a pretty profound effect on her. She went from cold and distant to sad and worried. Especially since my actions after that SHOWED that what I had said was true. Once I went from pressure and pursuit to moving onward and upward, her thinking started to shift from wanting out to being worried about what she stood to lose.
So yes, if he believes you are moving on more than likely you will see some changes. 180s have an effect on the WAS. Just remain consistent.
