Been working on that myself for a coupla years now!
But, this is my issue. Not my W's. Same goes for you.
I think you're right. It's part of the recovery process. You just hafta suck it in and wait it out.
My only advice is... Do not share this insecurity with your W. Do whatever it takes to keep your PMA going - especially when you're with her. She must not know about these feelings.
You're trying to get the "normal" feelings back. By that, I mean for you and for your W.
You have to act normally until your feelings catch up. No matter how long it takes.
Do that, and you've accomplished what you set out to do.
