I just told my cousin’s daughter that about her 13 year old daughter. She has 2 younger ones she needs to look out for and let the 13 year old go or she will ruin everyone’s lives. This 13 year old started at 12. Running away, having sex with older boys, accusing family members of rape, etc. She has been removed from the home and the mom is fighting tooth and nail to get her back...while the girl doesn’t want to go back. She was placed with the dad’s grandfather who is lenient and lets her do what she wants. I said....there is no fixing her. Let her go. If you actually succeed in getting her back it will be worse than before.
It is a sad situation, but it is not worth the damage they inflict on others. If they are lying, they will take the whole family down with allegations of abuse. They will steal, get into drugs, just not worth it.
Either she's a budding sociopath, or those accusations were true.
