She dumped him. Sydney found out that he had been cheating on Francie, and she confronted him about it, and told him to tell her and threatened him. He didn't tell Francie, and Syd ends up telling her, Francie doesn't believe her blah blah blah, in the end, he gets dumped and Syd and Francie are still friends...sorry, I'm lazy, I dont' feel like giving a detailed description..for once! LMAO! Hope this helps a bit.
