I think that in your current situation you should throw a party when he doesn't contact you! First, you don't have to worry about walking on eggshells, you don't have to think that anything you say might (or I perhaps should say will) be used against you. Second, you can save yourself a lot of time, since you won't have to spend it trying to find deeper meanings in everything he says (there aren't any, but that won't stop you trying to find them)!
Look at his lack of contact as giving you an opportunity to focus on yourself. Become a stronger person, for yourself. It is really true that if you do this, you become more attractive to him (once he regains his sanity). And if he doesn't regain his sanity, you'll be better prepared to take on life yourself. Or with any future partner. In fact, I think you should look at any R you have with him as being a new R. You don't want to go back.
As Mishka said, right now you are not saving the M. You are saving yourself. Have at it!
