But how would she hear it from someone else -- the Retrouvaille folks -- if they have a precondition of "no active affair" before you do the weekend?
Before a couple attends a weekend, they are interviewed (separately), at least in our community. That is where the issues of unrecovering addictions and affairs are brought up, and each spouse is told that any third party involvement must end before attending the w/e.
Gotcha. So you know that "a currently active affair" violates their weekend rules, but you hope that they can help you enforce the boundary by signing up for the weekend anyway, hoping they'll do this pre-weekend interview to talk some sense into the cheating spouse.
