I'm SO not the person to correctly answer this - Sandi and Cadet probably are... but here is my educated guess:
The feeling of 'wanting to end the R' is detachment. That is GAL as we say around here. You're letting, or really NOT letting your wife control how you feel and act.
I'm just getting to a place in my own sitch where the GAL term means something. My emotions controlled me the first 2 months after BD; I'm still emotional, but now am able to objectively see possibilities of a future without my W.
Our stress to you, and why I'm on this BB, is that I believe in M with all my being. My wife, like yours, has issues. I made a comittment to her, and will not break it.
What is your view on marriage? This site exists for those who believe in hope, in that it's never too late.
There are cases where a marriage needs to end - no doubt. Physical violence, emotional abuse, children or other lives at risk, substance abuse, etc.
