It's been a while since I've looked at your situation but it seems like you are in the same place as you were several months ago. Has he really come no farther along in all this time? Is he still playing games with you regarding child support, visitation, financial support, and so on?
Are you really still so fixated on his behavior? You sound like someone griping about their teenage son, not a grown adult. It seems like you keep being dragged into the same arguments over and over again.
