Hello and welcome to Just Answer.
You have done all that is appropriate so far. I do think that counseling is a viable option so that you can receive intervention and coping strategies and your daughter can express her feelings about all of these issues. Private school is another alternative. I attended a private school from 3rd-12th grade. It was not a religious school which have been much more strict. The private school sheltered me greatly but in the long run, I am very grateful for the experience. Your daughter needs to dispose of that boyfriend which may be a very difficult process to do. She needs to be surrounded by positive people especially at school where the social pressures are tremendous. I would suggest a private school that has extremely rigid rules and regulations, has an excellent academic curricula, and a college preparatory program. Times are tough for many families in this difficult economy but if you can afford a private school, then go for it. Also, do not ever allow your daughter to feel like she is in control. You are the parent. You have authority as long as she is living under your roof.
I hope that this has helped. Please ACCEPT. Have a wonderful day.
