Jack and Corryn have been in an on-and-off relationship for two years. Jack claims every time they break up, Corryn stalks him – hiding out in the bushes near his house, crawling under his deck and even breaking into his house.

Corryn admits her behavior is “out of control” but she says Jack gives her mixed messages.

Both teens agree that they have gotten into physical altercations.

“She will not leave my property or my house, so I physically have to pick her up and put her outside of my house. And then after that, she will bang on the door,” Jack explains. “I just lose it, and that’s when I start getting physical with her.”
