Bobbi Kristina Brown, the daughter of Whitney Houston and Bobby Brown, was planning on breaking up with fiancé Nick Gordon on the day she was found face-down in the bathtub of her Roswell, Georgia residence.

Ian Halperin, the author of Whitney & Bobbi Kristina: The Deadly Price of Fame, told TheWrap on Friday that he has conclusive proof that Bobbi Kristina did, indeed, plan on ending it with Gordon.

“I have 1,000-percent proof” that Brown planned to break off her engagement with Gordon and kick him out of the house, Ian Halperin said of Whitney Houston’s daughter.

Halperin said the Bobbi Kristina struggled in the months leading up to the January incident with her relationship with Gordon having an incredibly negative impact on her life.

According to Halperin, Gordon’s jealousy got the better of him, leading to accuse Bobbi Kristina of having an affair with a drug dealer. He further claims Gordon “did a lot of things that she didn’t approve of.”

“She wanted out of the relationship,” Halperin said. “She was contemplating a move to Los Angeles to pursue an acting career.”

Halperin stressed that he in not claiming that there was foul play involved in her mishap. Instead, he maintains that Bobbi Kristina may have been plunged in cold water to revive her from an overdose.

“I maintain the plunge theory,” Halperin said.

“Regardless, the fact of the matter” is that Bobbi Kristina Brown wanted Gordon gone, Halperin said.
