OK, so I told DH that SD19 is dating a 26 year old man with six kids with at least three women, one of which is an infant. A man who is on probation for assault. A man with whom she spends a lot of time drinking. I told him SD19 lied and got DH to fund her trip out of town to drink and have sex with said boyfriend (cried poor about how it was work-related travel and he bought it).

Here's what NOT to do as a parent (which, you can assume, DH did):
-- Never call her up to discuss the situation in person.
-- Text her and say "you can do better."
-- Accept her lies at face value (she told him she did NOT take said boyfriend with her, despite the fact that there are pictures and posts on the Internet that prove otherwise).
-- Reward her by continuing to fund her activities and money wasting (chiropractic adjustment, pedicure, tanning, numerous parking tickets, etc.)

I give up. He wants her to be a lying, manipulative, rude, self-center, money-grasping brat. He wins.
