I think it's because women -- by the time they walk -- have typically already been planning their escape, emotionally, for 6-12 months or more. By the time they drop the bomb, they're DONE.
Yeah.......or put up with cr@p for ten years, THEN decide to walk-out. I don't condone what she's done, but the girl needed somebody other than the jerk you've been. You admitted in your other thread how badly you treated her, and THEN when you learn somebody is paying attention to the person you never showed any value to......suddenly the story changes.
Well, I hope you've decided that she is worth a lot more than the way you treated her, but I don't know that she thinks it's worth her pain to stay with "you". If you do get the opportunity to be a wonderful H, I hope you'll be smart enough to do it. It will take a heck of a lot longer than a work week, so you better gear up for the task.
People here have been telling you to ignore what she says, but you've ignored her for ten years and she found somebody else that paid attention. My advice is to listen to her express her needs and you may want to think how OM was fulfilling those needs for her.
I think you will find that what you use to do in the past will not work any longer.
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
