"Sydney loved him but then she fell out of love with him because the idealized vision in which she had of him was not true, was not the case," he told CNN. "She became disgusted with him after finding out that the person who she thought she was in love with was not indeed that person."
Colagiovanni, who said he has been involved in dozens of political campaigns around the country and works as a media consultant, said he and Leathers discussed selling the story. He told her she could use it as a "springboard for national attention to ride on to fame and fortune."
"I hope we make some $ out of it," she wrote. "There is not a doubt in my mind that we won't makes (sic) thousands and thousands of dollars," he replied.
Though it was CNN that contacted Colagiovanni, he said he wanted to share Leathers' messages to him and her correspondence with Weiner because he felt betrayed by her.
"I feel this was my story," he said. "I had cultivated this story. I sat on it for months. I was reluctant to release it because Sydney told me, 'Listen, I don't want this story to go out, I don't want anybody to know about it.'"
He said he asked her about 10 days ago what she was doing with the story, and she still told Colagiovanni she didn't want anyone to know about it.
"And then as everybody saw on TheDirty.com, the story did come out, so she misled me in her ideas of what she wanted to have happen here," Colagiovanni said. "So why I'm talking to you now is, I want my story to get out there."
He is hoping to sell his story somehow. "I'm not going to lie: I have bills to pay," he said. "Everybody does."
