The ex is so predictable in her idiocy

It's been over a week and no word from the ex on dad's request for spring break parenting time.  What she is going to do is wait until after Christmas to tell him no so that it is too late for him to get them at Christmas too.  She's predictable in her idiocy.

I knew this was going to happen and the plan was not to let her wait until after Christmas - to give her an either/or (either Christmas or Spring Break - pick one or the other) after a week of not hearing from her. 

The problem is, after what my stepson has done with the graphic song he wrote and posted online to a child's song the other day (to Wheels on the Bus), I don't want him around my younger kids right now.  I don't trust that he won't hurt them or expose them to inappropriate stuff (talk, material, etc.).  He did it frequently as a child and apparently, he hasn't outgrown it.
