Laurie, not the place for such things???? Paaaa!

You are doing a wonderful thing and giving a young woman and her family hope for the future. Believe me, they do not have a future if their lives stay as they are.

It will be tough but it is up to you at the end of the day how much you allow this young woman to depend on you. You can assure her that she is safe but after that emotional and financial help has to be handled very carefully.
Welcome her to your couch for as long as it takes her to find a job, somewhere to live and some confidence in her ability to take care of herself. Help and encourage her but you will do her no favours if you give up your bed and home for her. She needs to know that she is able to take care of herself and that she can be valued in a different and better way as an independant human. That is not how she will think of herself at the moment.
An abusive relationship turns you into a dependant so giving up your home and your bed will reinforce the belief that she needs to be taken care of.
A lot of, "Here is my couch for as long as you need it but I can see that won't be for long. You have been so strong to deal with the way things have been for you. All you need to do is realise it and redirect that strength and self control and you can do anything you want."
She had the strength to leave the relationship, a lot harder and more scary than most people can imagine. She did that. She can do anything!!!!

You are a star - although you probably feel overwhelmed, I would! You will look back on this time as a blessing - when it comes to an end.
You are changing lives.
