Brooke Hundley, ex-mistress to Steve Phillips, gave her side of the story Thursday morning, speaking out as to why she sent the cryptic four-page letter to Phillips' wife detailing her affair with the former ESPN sports analyst and the fear that, she says, kept her in the relationship.

Hundley told "Good Morning America" correspondent Kate Snow that her actions that led to Phillips' wife, Marni, making a 911 call were all "just an avenue to get people to pay attention."

"The same fear that I heard in [Marni] -- and I listened to the 911 call after the fact -- was a similar fear to how I felt."

Also a former ESPN employee, Hundley said she was scared of what Phillips could do to her job, saying, "I was in a situation where I felt like if I didn't do what was asked of me then everything I had worked for, for the past six years, everything I had done to establish myself as a successful media professional, could be gone like that."

The sports cable channel released the following statement to ET on Thursday: "ESPN has a clear and consistent policy against harassment in the workplace. We investigate all charges and take appropriate action."

Hundley told "GMA" that she understands that she brought on the scrutiny that she is facing and "takes responsibility" for her actions but said it was unintentional. "I've been called things by the public that no woman should ever be called," Hundley said, tearing up. "When Jay Leno was using my looks in his monologue to get a cheap laugh .... that was my breaking point."

Hundley said of her emotional state in the midst of the media coverage, "I had a friend who came and stayed with me because he was concerned ... that mentally I would not be able to take much more."

Hundley and Phillips' were both fired from ESPN in October following reports of their affair. Phillips' agent told "GMA" that the sports analyst remains in rehab for sex addiction. Marni Phillips has filed for divorce but Phillips' agent told the morning show that the couple is working to mend their marriage.
