Skimming through SAA to refresh your thoughts can't ever be wrong. I do it also and I'm divorced. <img src="/ubbt/images/graemlins/smile.gif" alt="" />

TFC, your WH is foggy and sitting on the fence. You must expect him to lie, to be defensive, and to attempt to prolong his contact with OW as long as he can. That's human nature. It's not very attractive, but it's natural. Accept that, do your confrontations and do your best Plan A, while preparing for Plan B. Don't worry about slips. No one does a perfect Plan A so don't expect that of yourself. Too much pressure. Telling him to leave wasn't that serious a fall from the wagon anyway.

Like I said, hang in there. Try to find whatever peace you can through your Plan A efforts, your friends, and family, okay?
