Sending you a big hug Heavy. That all sounds awful but you're handling it with grace and respect for yourself.
You can withstand it, and more I'm sure.
It sounds like your W is telling herself over and over that she's D'ing you, as she herself can't believe it. As mean as you may feel she is being, she must be hurting inside too. It's a big stretch but trying to have a bit of empathy for her may make it easier on you as well.
You're doing a great job, and should be proud of yourself.
