Oh sure you didn't need to hear that. You and your H had been having a lovely time and he was just such a downer on things...not to mention he abused the "wearing out your welcome" policy.
As for my H's XW, I'm not even worried about her. He wants nothing to do with her and she's honestly inconsequential to me. See I'm the type of person who, if I ever ran in to her and she tried to verbally tear me down, would slyly smile at her...envison Yosimite Sam in a hoop skirt, and make her wonder what in the hell I'm smiling about.
