H has already txtd me this am asking when we can talk more again.
I know the basic plan is first and foremost to listen to him. Is this a good time to specifically discuss what coming home would take (i.e., details of transparency plan?)
I think he needs to earn his way back in, and there's no time to start like the present. I would recommend you be unavailable to him for a few days -- busy, don'tchaknow! :o) -- and say something like "this weekend is going to be crazy; how about we talk more next week" . . . and maybe even throw in a "As nice as last nite was, I'm afraid this isn't so simple anymore" just to leave him hanging a bit.
And then yeah, figure out that short list of CORE DEALBREAKERS for yourself.
