Grmpy - I feel that even though our scenarios are quite a bit different, we seem to have a commonality that isn't found often on this board that my W and I also do not have kids.
Thus, like you presumably, my thought is that I need to get in front of her to show her my changes and this causes some type of pursuing behavior.
In absence of slight pursuit to find an excuse to meet, we don't have contact so it is hard to show her any of my changes. This has resulted in controlling or pursuing behavior in the past, so I'm wondering if you have had any good thoughts on how you manage being separated from your W without kids and still finding a reason to have opportunities to have contact at some point?
I am truly trying to work on myself, but it is hard not having any contact, and I'd love to find opportunities to talk/meet without pursuit.
