...problem with using it is that....You are confusing your inexperienced projection of the problem with it
succeeding ("
...she has actually told me that she is speaking with this fellow") with the real problem with its
application("
...because you're basically afraid of her reaction")
Do you think I had that recipe all made up, and ready to copy-and-paste here, just in case
you showed up? Dude, these are the pearls-of-wisdom (not mine, btw) that give EVERY BH the last, best hope to retrieve his marriage.
Let's cut through the nonsense here, lg123. If "talking" was her goal, she would have found a way to do that without all the trouble of moving out. WW is not merely "conversing" with POSOM, unless said conversation is along the lines of "You know, I really liked that part where you put my ankles up over your shoulders!"
You seem to be so beaten down that you do not even resent the damage she's doing to you! Okay, bucko, how about the damage an affair-caused divorce will do to your children?
1) The fraction of affairs that result in stable marriages is ridiculously small, primarily because they are between people whose initial relationship was founded on deceit and betrayal. There will be no "happy home-life" for your kids at Chez Cheaters.
2) Do some research and find the huge incidence of emotional/psychological pathologies occurring to children who are the "victims" of infidelity divorces.
3) Do some more research and discover the incidence of sexual mistreatment of girls (if you have any) by partners of their divorced mothers. The boys, conversely, suffer arguably worse, being raised primarily by their (now single) mothers, developing resentment toward their mothers' actions in bringing about the divorce, translating into problems developing close relationships with females over their lifetime. ("Hey, Mom was an easy piece; it seems all other females should be as well!")
Lastly, WW has told you she has a "relationship"

with this scumbag? So she's good with that? Then you should help her by telling Mommy, Daddy, every aunt and uncle, each cousin, all her friends, her coworkers, her religious leader, etc, of her new life, based on her betraying the one you and she had. If she's so "okay" with telling you, she should be "tickled" to have everyone know! (Wanna bet she ain't so thrilled?)
Pearl Harbor Day was four days past. Your position is akin to FDR apologizing to the Japanese emperor about the noise of the exploding American battleships causing ear-pain to the suffering Japanese pilots. The battle hasn't even begun, and you want to surrender!
