I can really empathize with your 'limbo' -- although my H's A is still super secret (in his mind, at least). I've been struggling with shining light on it (and so far have made the decision not to) but holding my tongue and acting 'as if' is so hard!!
And I have a feeling he has some crazy ideas about initating a D and still having free access to this house (he has a home office here) or even winding up here with OW and her kids (and ours!)
Is there any chance that your H is doing this to try to get you to be the one to leave the house? What's your position on this?
