Something else to consider while you have her there is finding a speech-language pathologist to work with her. Even once a week can give her a good start on learning things like social skills, body language, the idea that someone might feel differently about something than she does ("theory of mind") - I have a 14 year old who, up until a couple of years ago, was given the full alphabet soup of diagnoses. She was finally diagnosed with Asperger's, but also has ADD and probably a soft bipolar disorder of some sort. Once we got the AS identified and got her into some social skills training, everything else fell into place. She was kicked out of first grade for being too aggressive - now she's a very successful mainstreamed eighth grader who actually has friends!
Now, even though the clinicians are called speech-language pathologists, they don't just work with people with actual speech problems. They work with all types of communication issues, which includes the social skills and unspoken communication issues seen in people on the autism spectrum. I've found a link for you for the CT SLP Association - this is a referral list with quite a bit of info. It may just take a few sessions to get the ball rolling and a formal diagnosis to give to the school to get her the help she needs. I'm not sure of your custody situation, but there may be a way to get the courts to mandate that her father gets her the services she needs.
I hope things work out well for you all.
