CC, When in MLC, if the lips are moving...well, there will be some lies spread about. If he doesn't want you to know what he's doing, he may very well lie. If he's done something wrong and doesn't want to hear any grief, he'll lie. Some of them become such "professional" liars during mlc.
You are going to find that there is going to be a lot of things that you won't get while he's in crisis. Why? Because he is acting out emotionally and they aren't always rational when they say or do stuff. You can't make rational deductions if they don't know why they are doing the stuff they are doing.
I think it would be wise to have your friends stop advising you of what he's doing. It's not healthy for you to hear all of this stuff. Just my two cents.
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.
