Helping them with their choices of leaving the home, having an A, all that is only feeding them cake IMHO ...
CaliGuy,
I don't disagree with what you're saying; I think one of the big issues an LBS has is deciding the appropriate actions to take with the desired end result of saving the marriage. It's difficult to really know what's best.
But, I do want to point-out that for most of us, helping the spouse toward their choices (such as leaving the house) is a complete 180. Most of us cling to the WS at first and we resist the spouse's desire to leave and get a divorce. Helping a spouse leave is doing the unexpected (in most cases) and can help show the WS that the LBS is confident that they can have a happy life without the WS.
