Now, for the first time, Brown's aunt, Pat Houston,is sitting down with Kevin Frazier on Monday'sEntertainment Tonight to discuss the events that led to Brown's hospitalization and how the family is recovering after her death.
As Whitney Houston's manager, confidante and sister-in-law, Pat was like a second mother to Bobbi Kristina, and she says she was working on getting her niece help before the then 21-year-old was found unconscious in the bathtub at her home in Atlanta, Georgia.
"When we really found out that Krissy was in trouble, we were really making plans to do something about it," reveals Pat, who says she also wanted to send Bobbi Kristina to a rehab facility in Georgia, "but it came too late."
In a lawsuit obtained by ET, Brown's conservator, Bedelia C. Hargrove, allegesthat Nick Gordon injected Bobbi Kristina with a "toxic mixture"before she was found face down in the bathtub.
In a statement to ET, Nick Gordon's lawyers slammed the lawsuit filed against their client, claiming it is both "slanderous and meritless."
"Nick has been heartbroken and destroyed over the loss of his love and it's shameful that such baseless allegations have been presented publicly," the statement reads. "Nick has engaged civil counsel and intends to defend the lawsuit vigorously and expose it for what it is: a fictitious assault against the person who loved Krissy most."
Pat always had her doubts and even filed a restraining order against Nick last year.
However, she admits that the restraining order didn't have the intended effect, because Bobbi Kristina "didn't understand it."
"Where the world saw that she was angry and mad at me, she was texting me all along," Pat says. "I really tried to show her [that] I'm going to do this to let you know that you don't have to be afraid of anything. I got you.'"
"External attraction can really cause problems," she adds, referring to the romantic relationship between Bobbi Kristina and Nick.
Dealing with the loss of Bobbi Kristina has been especially hard because the family still hasn't come to grips with her mother Whitney's death in 2012. In 2013, Pat and the family revisited the hotel room where Whitney died, and Pat recalls the experience.
"When we went into the room it was just so peaceful and calm and the room was lit -- it was like it was candle lit. It was just very, very calming," Pat says. "I went into the bathroom and I placed the flowers at the tub and I just sat there and just was thinking, 'What happened? How did we get here?'"
Three months after Bobbi Kristina's death at the age of 22, there is still a lot Pat wishes she could tell her niece. She opens up to Kevin about what she would have told Bobbi Kristina if she had the opportunity to speak with her again.
"You have to love yourself," Pat says. "You have to call on people and not allow someone to divide you and then conquer you."
Pat also responds to speculation that Bobbi Kristina's father, singer Bobby Brown, is going to write a memoir that would likely include stories about his ex-wife and his daughter.
"I don't really judge when it comes to that, you know? It could be something that could be very healing for him," Pat says. "You really never know what a person is going through so if he feels that he wants to write, he'll do it. But the only thing is you have to be very truthful. If it's good or bad, you have to own it."
