Maritimer, haven't caught up with your thread lately, but do whatever you need to do to make your kids first priority. You will indeed always be their father. Don't let anyone get in the way of your relationship with them. Your kids need you now more than ever. Ignore your W's emotions if she's being moody about you seeing them. Let her be mad and negative. Let her go on her journey.
Keep your PMA for yourself and your kids. They're watching you and need your security. You can do this!
