Matt-14, you've been at this a long time. You do realize that you were not the cause of your W's misery, don't you? Please don't expect that she will be happier now that you've moved out.
Has your W received any IC to help her identify the issues that she hasn't ever dealt with?
Is your W's RA under control? My oldest sister has it and it can be an insidious disease and a real zapper of strength and PMA. Does your W take any ADs?
How are your children dealing with you moving out?
I'm so sorry that you find yourself still here but you certainly have to be commended for hanging in there as long as you have.
