Quite a few triggers going on with your h. The crisis will take as long as it takes. There is no actual set timeline for when it ends. It all depends on him and if he can deal with his "internal demons" and heal from the emotional pain. Some will come through the crisis and return to the nomal selves, others will return to this world and continue to have some of the quirks they picked up along the way and others may never recover.
My xh's crisis began in late 1998 and he finally flew the coop in December 1999. We divorced in June 2002 and just last year, he finally woke up and apologized for destroying our marriage, etc. Of course, it was too late to try again. He was one of those that took forever and a day.
Try to remember that you will be the one who will decide if you want to try again, if and when he wakes up. Who knows? You just might have moved on by that time.
The stages and timelines you see written are just guidelines...nothing is set in stone because each person is unique and their crisis will be unique.
