Johanna, you did good. Most people in your place would have said "Oh, that's terrible." when they heard the news, and that is as far as it would have went.

I agree that you should just try to be around if you see her out and about. You don't have to push a friendship, but let her know that you are there if she does want/need help. Many times, like others have mentioned, women in her situation are cut off from family and friends, or they might not want to let family and friends know what is really going on - the camelot syndrome. She might be much more likely to open up to a "stranger" and might be more likely to take an "outsiders" advice more than any other.

Also having the name, address and emergency phone number for the local battered women's shelter on hand would be extremely helpful.

I know this all puts you in a tough position because the last thing you want to do is bring danger on yourself and Jonah, but I think you're great for stepping up and trying to help - thanks.
