He feels he's been pushed up against the wall, so he's coming out lashing. I think he's hit the really angry stage because he's not getting what he wants. Don't respond back, but keep the text message just in case you need it later on.
His hissy fit will need to settle down and it might take a while, but I certainly wouldn't change the appointments for the kids. He's exerting his "power" to manipulate you into doing what he wants. Don't do it.
He certainly doesn't like the idea of you not playing along w/what he wants. Poor boo boo. Life really is a @itch for them. LOL!
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
