I'm glad to hear that you and the kids are ok! That's the most important thing!
I don't think I would read much into H's words or actions one way or the other. I think he is probably pretty well shaken up, too. Even if he wasn't concerned about you (and I think he probably was), he was certainly worried about the kids. And probably pretty scared. Stress like that brings out the best and the worst in people, sometimes at the same time.
Unless you have to, I don't think I would make any decisions about Tuesday just yet. By tomorrow the shock of the accident will be wearing off, you will know every one is ok, and you may be fine to go ahead with things. If not, then postpone.
More hugs! And I am really glad no one was seriously hurt!
