LOL. I could almost see the light bulb going off the way you wrote that.
Good for you. My W is trying to do the same thing to me. For a lot of reasons that I will not go into on your thread.
JoAnn and friends on these forums have advised me NOT to enable her or Divorce her.
I basically told her(not the actual way, because it was modified) "I don't want a divorce, but I understand you do and I will not try to stop you. To be honest I don't want to be with anyone that doesn't want to be with me, but I will not do the work of divorcing you. That's your choice, not mine."
He wants out? He does the work. In the mean time keep working on you and being strong to yourself. I'm going to say this the only way I know how, you are probably going to get angry at some point, but you really need to act from a place of compassion for him. Look at it as an understanding of what he may be going through. Not the actual A part, because that's just flat out HIS wrong choice and who the hell know's EXACTLY why they do anything they do. Rather focus on what you could do to make him see what he will be missing and have the mindset of "His Loss, Not mine".
