Talk to a lawyer and start documenting as much as possible. Get yourself and son into counseling, and dad, too, if he is willing.

If they aren't back by morning, I would not hesitate to call the police and also a women's crisis center. They would have much information and contacts with which to help in such a situation; in fact, I'd call a women's center now, if there is one available. Susan is right; get local, in-the-flesh help asap.

With all good wishes,
