To help with PMA, try not to read texts or emails between W and OW. Right now, they're high on A dopamine. And what's that comment about "your mistress" all about?! You know it's best to zip it about the OW.
Trust me...things are not always rosy. I've been here for almost 10 year and many LBS report that their spouses open up about their life with XOM/XOW...it is NEVER what you imagined. Don't engage in thoughts that they're happy and all is rainbows, cotton candy and popsciles. It is ALWAYS ht opposite.
Why do the WASes declare that they're much happier and better off with the OW/OM? Because they want to give you the impression that they've made the right decision and they'd be damned to admit that they're wrong. So they persist in this type of narrative. Oh no...they just don't want to climb down and admit any wrong doing.
