DD2, 14yo, is in a relationship. No.1 thing I don't approve of. The guy. No.2 thing I don't approve of. From her friends, I hear that he's hit her before, he's tried to cheat on her, and it doesn't look like he generally cares about her. I also hear that their relationship breaks up literally every other day and has become a joke in their form. What to tell her/ do?
