New account, but Ive been here for years. I need advice!

My Sd19 Still lives here at home with us. She still goes to private Christian school. (her 3rd senior year) I am pretty sure she is never going to graduate, as the school loves their 350 a month, and she "works at her own pace". She has a 27 year old boyfriend. He is not really allowed here, but she goes to his house and spends the weekends.
