Jennifer wrote to Dr. Phil saying she believes the only way her best friend, Heather, will be leaving her relationship is inside of a body bag. Heather says she doesn't believe Collin is abusive, although she does admit that he has put his hands on her, ripped her clothing, and bitten her face. Collin admits that he once put his hands on Heather's throat while in a rage but says he never actually squeezed – although he did think about it. Collin says he doesn't believe he's in love with Heather like he used to be – so why are they both still fighting so hard to make this relationship work? And, is Collin actually abusive, or is he "not that bad" like Heather claims?
