I don't think it would have mattered because once they enter MLC, their past life becomes the past and they live in the present fully. If you do have contact w/him, treat him as you would a long lost relative. Listen to what he has to say and do not offer up advice unless he asks for it.
We all have wonder at times about the way we handled things...but once they begin their crisis, things change quite a bit and what we would have done in a normal situation becomes moot because you can't rationalize w/someone who fully charged emotionally.
Focus on today as it is a gift, tomorrow has not revealed itself and the past is gone and we can't change it.
You've give him the best gifts of all: time, space and more time. This is what he needs. You will need to dig deeper for more patience as the MLCer will surely try your patience along the way. When he's ready, he will contact you.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
