I feel for you but... Your H's no contact on your last day is standard script.
And if you think about it, it shows that he still does care about what you do. First time in 9 years that he hasn't called and it's the day before you leave....
Likewise with the school stuff. He's still struggling with what he's doing to you and S because he can't help but get angry, no matter what you do.
He has to work his way through all this junk.
In the meantime, enjoy your trip and take all of our best wishes with you.
