Matthew Perry's stepfather Keith Morrison says actor 'felt like he was beating' addiction before death

It's been nearly five months since beloved "Friends" star Matthew Perry passed away. 

His stepfather, Canadian broadcaster and "Dateline" correspondent Keith Morrison, is addressing Perry's absence, admitting the grief is difficult and the circumstances are "not fair."

"He felt like he was beating it. But you never beat it, and he knew that, too," Morrison said of Perry's past with addiction while appearing on Hoda Kotb's podcast, "Making Space."

"He was happy, and he said so. And he hadn't said that for a long time," Morrison admitted. "It's a source of comfort, but also, you know he didn't get to have his third act, and that's not fair."

An autopsy report revealed in December that Perry died from acute effects of ketamine. Coronary artery disease and buprenorphrine effects were also listed as additional conditions that contributed to his death. The actor was found dead in a hot tub at his Los Angeles home in October.

"As other people have told me, hundreds of times, it doesn't go away. It’s with you every day. It’s with you all the time, and there’s some new aspect of it that assaults your brain," Morrison said of the grieving process. "It’s not easy. Especially for his mom," referencing his wife, Suzanne.

"Toward the end of his life, they were closer than I've seen them – had seen them for decades. Texting each other constantly. Him sharing things with her that most middle-aged men don't share with their mothers."

"He was a larger-than-life person," Morrison added of Perry. "He was always the center of attention everywhere he went… That kind of personality. He was goofy, he was funny, he was acerbic. But even if he didn't say a word, he was the center of attention."

"It's gone, but you still feel the echo of it everywhere," he said of Perry's presence.
