Sorry to hear about you not sleeping. I've found it very tough to have a sense of normalcy too. Family says I've lost weight and look too thin, and I'm definently not sleeping enough (2 hrs last night). Just try to keep your PMA going and realize that some things are out of your hands. Your only choice is to have a good day tomorrow and if he wants to be a part of it all the better, but not the end of the world if he doesn't.
Our stories seem somewhat similar - married very shortly and spouse throwing in the towel. Very frustrating but we'll get through it.
