Believe none of what the WAS/MLCer says for it is all a smokescreen to cover up their unhappiness.
We are pretty good at shouting from the rooftop that we're happier and living it up with the OW/OM. In reality, it is the opposite and we would NEVER admit it to you because it would be admitting we are "wrong" about our choices/path. Embarassment and shame are what usually prevents them from coming home because we hate being judged.
The OW/OM is a cortisone shot that relieves pain temporarily. Trust me on this one. Heck, Cali's W just recently admitted to Cali that the XOM wasn't all he was cracked up to be.
It is not a matter of your W getting what "she wanted", but wanting the temporary fix to her own inner demons. You don't want to be in a MLCer's shoes.
Go back and re-read the link about my own MLC experience.
You are dwelling too much on "she got what wanted" when in reality she is at the bottom of the well pit.
Just bide your time and it all will be revealed in due course when her A crashes and burns.
