Country music legend Glen Campbell's wife has spoken out about her decision to move the singer to an Alzheimer's care facility, revealing it was too exhausting to look after the legend at home. The Rhinestone Cowboy hitmaker was admitted to a Nashville, Tennessee centre for his own safety and Kim Woolen, his partner of 31 years, insists it was time to seek professional help. She tells People.com, "There were five of us taking care of him and we were all completely exhausted. "No one was getting any sleep and we were just struggling every second to keep him safe - we felt like it wasn't safe anymore." Campbell is living in the facility full time, but he is able to return to the family home. However, his wife reveals his visits are not always easy: "You have to watch him every single second. He's up all hours of the night and wanders. He'll pick up knives and sometimes he won't want to relinquish it." His daughter Ashley adds, "(It can be dangerous) with all the household appliances and dish soap liquid and olive oil. He'll drink anything... if you lose concentration for a second, he could hurt himself." Campbell has been in the facility since the end of March (14). Woolen says, "He's made friends there. Everybody loves him there. It's a beautiful setting, it's very secure. He plays guitar there..." The singer has been suffering from the disease for over three years, and headed out on a farewell tour in 2012.
