What happened to Canaan?

He was such a huge part of S1 and S2, but after he and Kimberly called it quits, he just disappeared. I would have imagined that he and Whitney would've talked soon after. Whitney probably would have said she needed some time being single, but their continued attraction could've loomed over the season. There's still time left in the show, but this seemed like such a missed opportunity. Where did he go??
