I would really say the "nudges" are doing what you are doing, especially with the LL stuff. Subtle, but helping him think that his happiness is actually with you (until or unless he finally realizes that his happiness actually comes from within )
It is generally recommended that LBS keep mum regarding the sitch, except to Drs, Ls, therapists, here. For those in the LBS's personal life that know, it is OK to be honest but otherwise indicate that you appreciate their interest and that you would prefer not to discuss it. At the same time, shame is a horrible thing that can be very harmful. Hopefully, a LBS can get past the pain and realize there is no shame to being a LBS, even if the WAS/MLCer speaks poorly, publicly, regarding the LBS, or if there is an OP.
Also, keep in mind that if you aren't prepared to talk about it now, IF the M ended, why would you consider talking about it then? I think too often that happens only so the LBS can feel some vindication.
