This is DETACHMENT. That means I live my life for me, and I shut her OUT so she can FEEL what life without me is like, which includes rejecting her attempts to 'act normal' with me. Our life is no longer 'normal'
Living life for you....that's great. Detaching for you sanity and self-development is key.
Shutting her our so she can feel what life is like without you?Hmmmmm. Isn't that acting in a certain way so you can get a result from her? Isn't that a form of FIXING, albeit in a round about way? It's what you did last time: played hard-ball as a last-ditch strategy to get her to taste what life was like outside the nest?
It's not that detaching doesn't, on occasion, cause the WAW to wake up. Perhaps it's the intention behind it.
I think if you don't want to be around her, fine. I think if you don't wish to share "good moments" with a wife who is pursuing another man, fine. But I'm not sure that creating a relational strtegy to teach her a lesson is all that healthy for you, even if gets the intended result.
