I think you need to be very, very careful with MIL. She could be a powerful ally, a serious liability, or a real deep operative bent on your destruction.
Be friendly but guarded with her. Do not mention DR, as it is your real ace in the hole. If you worry about having insights that seem to come from nowhere, add some other books to your library, like "The Truth about Love" or "Passages", even Dr. Phil may buy you some room. Be the man with the plan, just resist letting your hand show, know what I mean?
I hope she is really on your side, but I fell for the "we are on your side, you will always be welcome in our house" speech too, and I'm still trying to recover from the damage.
Sorry to sound cynical, but I'm speaking from hard won experience. Hope it helps.
P.S. Really sounds like you are doing great. If you have the time to read "Deep Survival", you may find that the traits most common to those that survive extreme situations are ones that you yourself have in spades. (Geez, enough card analogies, WC) You've hit the ground running, just keep it up (and don't beat yourself up too bad if you have a stumble or two).
