I once thought that being in a relationship would make me happier, but I've had enough vicarious experience with women and experience with women on a platonic level to realize that being in a relationship is, most of the time, not all it's cracked up to be.
You see, the thing you've got to realize is that women are people too (I know! Crazy, right?). What I mean by that, specifically, is that they're going to have their own wants, needs, dreams for the future, etc.; and frequently those wants/needs/desires/etc. will clash with yours. That, and you need a lot of face-time with most people before you discover their flaws. You might walk past your high-school crush every day on your way to your locker and say hi, but that's not going to tell you if she's got a gambling problem or a genetic susceptibility to alcoholism.
The corollary to that is that a lot of what most people consider "love" is based solely around stuff that's going on in their head, instead of the real world. I imagine we've all had the experience of "putting someone up on a pedestal", only to realize later on that you were just making shit up.
I think being in love can be as good as the hype, but the catch is you have to work really hard to attract them to you, keep them interested, and do those things in a way that doesn't drain all your mental and fiscal resources, make the relationship work, and find someone who is willing to work as hard as you are on those things. It's a difficult skill to learn, and for me, the expense (in time and energy) vs. reward is waaaaaay too lopsided for me to want to bother with it right now.
So, yeah. Happy being alone. At least for now.
