So sorry w/ how your feeling lately JKS, the pain can be almost unbearable at times. You are not alone in this and we are here to support you.
The acts of our WAS's never cease to amaze me and can be so frustrating and destructful. I can't believe your h asked your 4-year old to essentially lie to you, that is just so wrong IMO.
What are your GAL activities? Try to just focus on those and your kids. Even if they are small steps they gain momentum and really helped me detach from the mess I felt my w was creating.
