ETA: Btw, I taught foster parent certification classes SPECIFICALLY on dealing with girls who are provocative towards foster family members, particularly the fathers, WHY they do this, and how to RESPOND to it.
ALSO, I don't tell this story often, as I have HAPPILY moved on with my life, but my college-teaching husband of 20 years had an affair with a 17 year old student. So I've seen this game from both sides of the fence. I STRONGLY believe this man abused this vulnerable young girl with emotional issues (even if SHE came on to HIM) and until we put these people innprison for it, others will continue to follow suit. This destroys lives, but keeping narcissistic sociopaths from destroying others around them for their own entertainment is a hard hard job.
