If I had to do my sitch again, I would have walked out the day I saw the texts, not said a word to her, just walked out the door and waited a couple of months before any contact. that way I could of let her do her journey without me having to see it, you can't stop the journey and I wasn't strong enough to deal with the thought of them together.
There have been WW's to come to the board saying that's exactly what their H did.......and it was him immediately walking out on her that had her in tears and begging for help from the forum, b/c it yanked her out of the fog or fantasy (whatever you want to call it) and she became the LBW.
Personally, I agree with Coconut, and believe that action would be very effective in most cases with a WW. The problem is trying to convince the newcomers. First, they won't do it, and they have a zillion excuses for not walking away. (It all boils down to fear). The majority of LBH's in newcomers fit the descrription of the NGS......and nice-guys just don't work that way. Second, I'm sure hands would be smacked if that became routine advice on a M saving forum.
IMHO, the effectiveness comes in walking away immediately upon learning about the OM. That's why dropping the rope works so well. However, by the time a lot of guys come to the board, they have been in their stitch for weeks/months. When the H waits around trying to do this & that, she knows he's not going anywhere anytime soon. So, she continues to play him.
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!
