"I'm on the same journey as everyone else," the musician tells Ellen DeGeneres

Just one month since John Mayer and Katy Perry called it quits, the singer-songwriter is finally opening up about his time with pop star. Sort of.

In an interview with Ellen DeGeneres airing Tuesday, the talk show host prods the musician, 35, about his time with Perry, 28. “It’s nobody’s business but …” she starts.

But Mayer doesn’t divulge too much about what went wrong between the two, saying his relationship with the singer was “private.”

“Listen,” he says. “It was a very private relationship going in. It was a private relationship during and it’s a private relationship, still. I can understand asking the question.” Later, Mayer adds, “I’m on the same journey as everyone else. Coupling is a tricky thing.”

For a man who once compared ex-girlfriend Jessica Simpson to sexual napalm and talked candidly about dating Jennifer Aniston, Mayer isn’t as revealing about his romance with Perry – and he suggests that he’s learned to keep some details about his exes to himself.

“I can understand asking the question [about Perry] based on some previous answers I have given,” he notes. “But I have finally learned how to put the wall between one thing and the other. I’ve been much happier since then.”

Despite the split and surgeries, Mayer – who will tour this summer behind his latest album Born and Raised – says he’s not too broken up about the changes but admits, “I’m a little more boring now.”
