Phoenix Suns CEO Rick Welts has resigned from his post, roughly four months after announcing he's gay.

Welts told the Arizona Republic that the decision to leave was personal.

“The most important thing for me is to get my personal and professional lives better aligned,” said Welts, a reference to his relationship with his partner, who lives in Sacramento. “They've probably never been aligned. I'm 58 years old and it's time to do that.”

“This isn't one of those departures to see greener pastures. It really is completely a personal situation. These guys have been tremendously accommodating and any other inference than that is absolutely crazy.”

Welts came out gay in an interview with The New York Times at about the same time as CNN anchor Don Lemon.

Shortly after coming out, Welts told CNN's In The Arena that he supports gay marriage.

“I look at the word 'equal' and I'm still looking for that asterisk,” he answered when asked his opinion on the issue. “I can't really see where that is.”

Welts had roughly 10 months left on his contract. He will be replaced on an interim basis by general counsel Jason Rowley.

He added that he's considering writing a book.
