Live and learn - you should have called the cops - but what's done is done.
I am no lawyer and in no position to give legal advice, but if it were me, I'd stop trying to deal with the husband (doesn't seem like you're going to get far) and call my insurance. Typically, your insurance will be much easier to deal with and they'll just go after the other person's insurance company after all is said and done. However, I am not sure if this is too late or not since you contacted the other insurance company? You can always call and ask. Anyways, good luck and I hope everything works out!
