Hey, GREAT suggestion, tu! I was sort of in a quandary, myself, but calling on a DV group is an EXCELLENT idea. I don't believe most places put any kind of time limit on providing assistance or referrals that may help.
Of course, the problem may still be getting her to see that it is critical that she do SOMETHING about this situation.
Good luck getting through to her, Happy--I hope she follows through. Her son deserves it.
