What Is The Reality With Bobbi Kristina Brown And Her "Brother"

All this week there have been stories and even photos of Bobbi Kristina Brown and the guy she has always thought of as a brother making out and groping each other while reports are they are engaged. Cissy Houston seemed to confirm the engagement when she said it is incestuous and Bobbi told everyone to butt out. She then displayed an engagement ring which she took from her mother's jewelry box. So, to me all that means they are engaged. But hang on a second. Nick Gordon says they are just friends. Huh? So, the whole making out and groping each other? That is just the way everyone says hello in the family? That must be one amazing family reunion. They could have Pay Per View for that.
