Hang in there buddy. I am so very sorry about this. AndrewP was right - learn the laws. I know in many states, people with kids must live physically separated for 1 year. Some even longer.
Perhaps if your state is like that and it will buy you time. Time is your friend as long as you can stick to your 180 guns and keep focus on yourself.
When the house goes up for sale, the kids have to go to a different school, the payment schedule is discussed - that stuff can get pretty scary, so yeah time is your friend.
If you can I hope you find time to get out and do ANYTHING positive that is just for you.
If you can't get out - we're all here for you.
