Inevitable always happens

[CWOL]

I think we are DB twins, lol.
For my WW, there's no chance that she will get together with her XBF, he's on another continent and he told her "I can't leave my family obligations here." (I was able to "hear" their conversations). I think it's the same as your WW, they're weak to others but they want to "show" us how strong they are, for their pride and the imaginary "abuse" they took from us during the marriage.
My exposure of her EA blew that to shreds. She couldn't use her story about us not being compatible, she was miserable, etc. when I showed people she reconnected with OM 9 years ago! Her arguments didn't have a leg to stand on. But now she persists in her actions because she has to show people that our M was so bad she has to leave. Nevermind blowing up everything I've worked for for 20 years and making both me and my S miserable. (And I'm sure herself too!)
It's so unnecessary but I don't see a way out of it. I wish I have a time machine so I can just fast forward to see the ending first. We are stuck in this purgatory while our WW figure out what they want to do in life. This part is what I really hate. It is very unfair that I am the faithful spouse yet she can spew all this venom and hate on me and my son and destroy our family. With seemingly little repercussion.
