Will, You have your hands full before the bomb, sorry you are here but it's the place to be.
So your wife has no job, is disabled, can't care for your son, and wants to D you? Any issues presented by her? She has been thru the wringer, do you think you is trying to push you away so you have a "better" wife? Is she depressed?
Read other sitches, do your homework, have a open mind, try new things and do the work.
Cheers Coach
