Story highlights Football player-turned-actor Terry Crews says he overcame an addiction to pornography

Crews: "It affected everything. My wife was literally like, 'I don't know you anymore' "

(CNN) "Brooklyn Nine-Nine" actor Terry Crews is opening up about his addiction to pornography, which he says "really, really messed up my life."

In a new series of videos posted to Facebook, the former NFL player says he had to go to rehab for his addiction, which consumed him and threatened his marriage.

"Some people say, 'Hey, man ... you can't really be addicted to pornography.' But I'm gonna tell you something: If day turns into night and you are still watching, you probably have got a problem. And that was me," he said.

"It changes the way you think about people. People become objects. People become body parts; they become things to be used rather than people to be loved."

Crews said he kept his porn habit secret from everyone, including his wife. He and singer Rebecca King Crews have been married since 1990 and have five children.
