Oh Lord SPM, I am so sorry, didnt have time to read all this but all I saw was your profile and said to myself, let me check this out. I too have 4 kids, 14 yrs of marriage, W is 37, controlling, abusive to the kids blah, blah, blah. Some has merit, most does not.
You sound so strong, your W has made this VERY difficult on you. I am in a VERY similar sitch, although my W did not change locks and have an A (as far as I know), VERY similar.
I will keep reading when I have time. Kindred spirits my friend, just know there is someone out there who is feeling all the feelings you are and has been down a similar path.
Best C
