Great post! It is pretty amazing what a change in POV can do. ...and your description of how it goes from "acting as if" to actually feeling it, is bang on!
I'm so sorry to hear that after all that your H cheated again ...But KUDOS to you for coming to the realization that it had nothing to do with the excellent DB work that came before...nothing to do with YOU...
Is your H working on those boundary issues? Seems to be a problem with lots of the H's around here.
