I actually had heard about this and wondered whether it would have been a good idea before our D. But, in reviewing this writeup on this, I have to say, I am not certain this would be a workable solution for couples where one is MLC. The main reason being:
•One partner has made an final, irrevocable decision to divorce and only wants counseling to encourage the other spouse accept that decision.
Since in most MLC cases especially those with an alienator active and on the scene, I don't think you would get very many results other than a faster run to the D. From what I have observed, many of the MLCrs are happy just plugging along and won't do much in the way of actively working towards the D, but this would get them thinking more about that option. IMO.
Anything truly worthwhile in life takes wisdom, effort and energy.
