WHG - I think as bad as things are, you are doing the best you can, all things considered. Going dark is probably going to be the hardest. But it will get easier as time goes on.
When you talk about your W calling you to vent and asking for favors and other ridiculous stuff so she can do selfish things (i.e. party's and bikini waxes) I can't help but remember something you wrote several weeks ago abut your W's former H.
Something about when her car broke down, how he came to help her because he was in denial about the demise of their R and how your W sort of laughed at his desperation.
Don't let your W trap you into that type of behavior. Your W needs to realize that she has made her bed and needs to lie in it.
I am actually feeling anger towards your W's behavior! Is that rational?
Anyway, keep reading through Busto's thread and see the tactic he deployed when it came to managing his W's cake eating and how he set certain boundaries that ultimately led them to reconcile.
