I don't have any advise, but it sounds like you have a well organized and well thought out plan to implement while husband is involved in active affair. You seem to understand the amount of patience necessary and I am rooting you on!
As an outsider reading in, I feel like husband really would have to be a fool to permanently leave. You seem to have figured it out, that it won't be possible to work unless he rally wants it to and returns remourseful. Good for you.
I believe we are on the same time line (I posted as julie). Are you comfortable putting a profile up?
