On only did she use her privillege ( you do realize sleeping with her boy boyfriend as an undersigned teen in your home is a privilege, not a right , I hope) she spoke to you with the utmost disrespect about your sex life to you and in front of her boyfriend! I would have pulled over the car and told her she's walking home. She has taken this privillege used it as blackmail and then talked to her as daughter should never speak to her father.
I, personally as a parent would take the privillege of her having sex with her boyfriend under your roof away and punish her. Not even for the blackmail, but for the way she spoke to you . Has she ever had any consequences to her action?
