I am not one of those cheerleader types of posters even if some may think so but in your case, it struck me as odd that you had this talk, right after the library book thing. It is pathetic to base your M on a freakin library book but to them it is the "the same old story repating" hopelessness feeling they get. I get it myself now with H.
Stay low, respect what your H is telling you. He wants out, fine. Do what a separated/divorced to be, woman would do. Just be polite and NOT eager to "finish up business". But do respect his feelings. Let's see how serious he is about it. K
