One quick question - the more i read, the more sense i get that she is the one who has detached from me , ie, she is following the DB playbook and maybe i am misinterpreting detached as WAW.
I'm no vet, but your last point is one that I have thought myself about my situation. In your W's mind she may well consider herself a LBW...you may be a WAH or WW...just that your mistress was your own selfishness and/or career ambitions...that you prioritized that over her...when she doesn't feel valued, then she emotionally (and physically) checks out...resentment builds...she gets angry...
