FIB, first things first. You remember Tyson (tiara Boy/confused mess)? He used his threads as documentation for court when he got his kids away from their mom. Make sure you are printing out all of this documentation and keeping a file of her actions.
As far as the game goes, do you have Friday off? Take your son out... all day if necessary and then take him to that game. There comes a point where you stop letting her do the strong arm crap and simply do what you need to do. Her insane behaviors at this point seem as though it would be enough for a judge to deal with her already. Do you have a guardian ad lidem for the kids? If not, get one now.
Her behaviors in front of the kids would be classified as harmful and dangerous for your children. Then satan comment put sit over the top. Get a Guardian involved and get your kids protected from hearing anymore nonsense.
Reality check time. She is pulling this crap to get you to quit. She wants you to get frustrated and move out. She wants you to "break" and she obviously will go to any lengths to get you to. It may be time to get her evaluated psychologically. Get the Guardian Ad Lidem in place and see what their thoughts are about it.
Bottom line at this point is that she is now doing mental damage to your children and you need to take a stance and stop this. Do whatever you have to do to protect them. If your still up tonight and need to talk...holler.....
