(CBS) When NBA center Jason Collins came out of the closet in April, the announcement hit especially close to home for one person in particular – his ex-fiance, Carolyn Moos.

The former WNBA player, who dated Collins for eight years, says she had absolutely no idea Collins was gay. The two were even engaged to be married, only to have Collins inexplicably break off the engagement one month before the wedding.

In a piece written for Cosmopolitan magazine, Moos opens up about the entire situation.

In the years that followed, I dated other men, I built up my business, I had a full life. But when it came to Jason, deep sadness and confusion remained.

The phone call this April ended the mystery. He left a message on a Sunday, saying, “I have something important to talk about—please call me back.” I was working and called the next morning. He uttered an eerily familiar phrase: “You may want to sit down.” Then he said, “Carolyn, I’m gay.” I was stunned. I managed to say, after a silent moment and then a deep breath, “I had no idea. I’m sure a huge weight is off your shoulders.” During all the years I had known him, I never would have guessed that he would come out as gay.

We talked again briefly that night. He answered a few questions, but there was much left to discuss and he said he had to go. As I tell this story, it has been several weeks since he told me his news and he has made no further time to talk, despite saying he would do so. I am sad that the media seems to be a higher priority. I hope this changes in the coming weeks, as I value open dialogue more than anything.
