Many of Whitney Houston's fans have long blamed Bobby Brown for her troubles.
They were married for 15 stormy years until their 2007 divorce.
Brown took the stage with his band just hours after Houston's death, and he broke down several times during the performance.
When Houston met Brown in 1989, it was the good girl who grew up singing in the gospel choir falling for the bad boy.
In an interview in 1992 with NBC, Houston said, "Yes, Bobby is the man in my life and I'm very much in love and I'm very happy."Special section, Whitney Houston: Death of a pop diva
Whitney's last performance
After the two married in 1992 at Houston's lavish New Jersey estate, she told Rolling Stone magazine, "When you love, you love. I mean, do you stop loving somebody because you have different images? I am nobody's angel."
Houston's career was on the rise. The year she married Brown, she also starred in "The Bodyguard" and recorded the film's blockbuster soundtrack.
In 1993, she gave birth to their only child, Bobbie Christina. But by the late 1990s the couple was constant tabloid fodder, dubbed the new Ike and Tina Turner. Their relationship was rumored to be riddled with drugs and alcohol. In 2000, airport security guards in Hawaii found marijuana in their luggage.
That same year, Houston started canceling concerts at the last minute. In an interview with ABC News' Diane Sawyer in 2002, she admitted to struggling with alcohol and drugs, but defiantly denied using crack cocaine.
"Crack is cheap," she said. "I make too much money to ever smoke crack. Let's get that straight, OK? We don't do crack. We don't do that. Crack is wack."
In 2003, Brown was charged with battery. Houston says he hit her during a dispute, but she stood by him in court.
The couple took their tumultuous relationship public in the 2005 reality series "Being Bobby Brown" creating even more tabloid headlines. Houston filed for divorce a year later.
During her recent attempt at a comeback, those years of hard living had finally confined Houston's once limitless voice.
She admitted that, ultimately, Brown was her drug -- an addiction to a love she couldn't quite break.
Brown has now left his music tour. He returned to Los Angeles on Sunday. He is asking for privacy for his family.
