I understand how you feel. Unfortunately, our stories are similar and I'm going through the same thing. At this point, there is no guidebook for this. You have to take it day by day and allow yourself and outlet to release your anger (exercise, shop, eat, etc.)so it wont stay pent up.

Don't try and understand him (because you wont). Use this time to work on yourself and being there for your kids.

PS.Y ou don't have to give anyone any details if you don't want to. Surround yourself about positive people as well...that helps.
