You're too funny, TS, and I see you get the flavor of SI.
I read the thread. It's a smattering of opinions, isn't it? The thing is that the workable solutions, when offered, are also opinionated against. That is, there isn't a foundation of support in that direction; opinions go back to "still, what they did was wrong!" sort of thinking. To be fair, that's found on quite a few sites, including this one.
The thing is that we come to these sites for help in turning around our situations. Even the person whose first thought upon becoming a LBS is to deal with it by thinking of divorce ought to be given another perspective, as divorce can be an inculcated knee jerk reaction; it's not a given that the solution to an A is divorce when indeed the A can be used as a wake up call instead.
What the affairee did will always be "wrong", there's no sense in staying there though if one wants to move ahead. Did you note how a few responses on that thread mentioned that the person couldn't move forward until they had learned to let go? In a real supportive board, where real solutions are discussed and implemented, that should not be the minority expressing that, that should be the majority.
BTW, Blondie was posting to me. Sheesh, it's not always about you!
