I don't think there's such a thing as "too long" in being single. You do what works best for you -- I know that sounds cliche, but it's true if you haven't met someone that's ideally suited for you. I would much rather be single for a long time than be with jerks, egotistical guys, etc. I lucked out in finding a wonderful guy a few years back, but if I hadn't, I'd rather have stayed single.
