Yes, following this his colon ruptured, he was in a coma and he had heart problems, iirc. I don't think he was healthy enough to reopen the sober house but, I still give him credit for running it for as long as he was able. He went the opposite direction of someone like Charlie Sheen who leaned into his addiction. Matthew tried again and again to get better and used his resources to help others, which I hope people will remember as part of his legacy.He did open a sober house for men from his former home in Malibu for a few years, but in 2015, sold that home and said he'd find another location to open a similar facility. That never occurred.
My take on it is that we sometimes forget just how hard a battle against opioid addictions is. It's easy to say he rifled through cabinets for anything he could get, or he was a difficult person to be around, but it's a disease, and addicts do get desperate and do desperate things. By all accounts from those who worked with him, he was just a deeply sad man whose addictions isolated him, but he never gave up trying to be better and he always helped others.
May he have the peace now that he couldn't get in life.
