But first: GaGa, that's the second time you've stolen my tagline. :p Of course I'm flattered, but maybe I should trademark it to help fund my sugar budget. LOL But you are correct; Life is good!
As to the new BF, I predict, as have Fish and GaGa that he won't last. He's already showing his lack of respect, insecurity, and general asshole-like nature by showing up unannounced, even after he's been told not to so do.
She's going to either get tired of that type of behavior, as I believe it will only increase. Or she will take the "blue pill" and go all in with him out of some misguided aspect of her own insecurity, feeling she doesn't deserve a "nice guy" who respects and admires her (that would be you!).
Either way, you can only observe, keep being there when she needs/wants you, and be prepared for her to either go or stay.
Of course, you could also take a page from PaPa Sweet's playbook and start to sell the wife on the idea of buying an RV for vacations. Then you can take the Rig out for a spin every few days to support your meet ups sans hotel bills...
Life IS Good!
