FLTC: Sorry to hear your soon-to-be ex is still so angry and difficult. I hate to say it - but some of them never get out of that stage. For me it has been 8 years and he is just as nasty and difficult as ever. And I don't get ANYTHING from him - just grief. I don't get any of his pay or CS or anything - still he is horrible to me. So - getting this part done will be freeing for you.
Life gets better. This you're finding out. Glad to hear that things are going wo well with gym woman - sure changes the focus, right?
Anyway, just here to say "hang in there" - it will soon be over and you can get on with your life.
