The Canadian has not fought since he announced he would be taking time off following his successful welterweight title defence against Johny Hendricks in November 2013.
The 33-year-old has at no stage committed to a return, and while White used to believe that St-Pierre would make a comeback, his hopes have faded, with the fighter now involved in other projects.
"I offered him a fight in Montreal, and he said 'I'm not ready yet,' " White told the Jay and Dan Podcast. "I'm on the fence, I'm leaning toward he's not coming back these days.
"He's rich and really doesn't doesn't have to do anything anymore if he doesn't want to," White added.
"He's filming some movies. You know the Jean-Claude Van Damme movie 'Kickboxer'? They're remaking it with him.
"So he's filming that, and he's doing some fun stuff. I was in L.A. one night and I went to the Clippers game, Georges St-Pierre is sitting over there in the front row. I went out one night to a concert, Georges St-Pierre is in the front row. Fighting is one of those sports that you got to be hungry, and you got to want it. He hasn't been hungry in a long time for a lot of things."
