Now, the star's wife of 32 years is defending her actions, saying she was told by doctors the move was "the best thing for Glen," who was diagnosed with Alzheimer's disease in 2011.
In a statement to the Associated Press, Woolen, 55, explained that she had a team of six people caring for the "Rhinestone Cowboy" singer, 78, around the clock at home, but Campbell's current doctor advised her in February about the need for 24-hour access to medical care.
"The doctors and my team know what care he needs, and they were an integral part of this family decision," Woolen said in the statement. "Our children, all of Glen's brothers and sisters and extended family support me as well as his daughter Kelli. It is very … hurtful to have people who are very far removed from our situation to be scrutinizing and judging our private family decision."
In May, Woolen told PEOPLE the memory-care facility near their Nashville home was "a very nurturing place" where Campbell feels secure.
"I sit with him through his meals … we hug each other and cuddle. I savor every day," she said.
At the facility, Campbell is able to participate in stimulating activities and therapy. "His life is filled with love and laughter, and he is being cared for 'round the clock by people who specialize in Alzheimer's care and happen to adore him," she said.
