Why do I always get flirted with by taken girls instead of single girls?

I'm 19, and basically am a friendly and sweet guy, but not the type of guy who's afraid of sex or anything, not the typical nice guy.

I noticed, that it seems basically every time I swear a girl is flirting with me and talking to me, she always ends up having a boyfriend. They don't normally tell me that have one, but I will end up either seeing them with one or overhearing them talk to someone else that they have one.

I've had girls that appeared to really be flirting with me, so I go and chat with them, and they appear to possibly even more like me, but then they end up having a boyfriend.

I never seem to have single girls flirting with me and I never seem to find single girls around 18-30, even in my college.

Is it a looks thing or a personality thing?

I just don't understand why I get girls that are taken, apparently flirting up a storm, yet single girls are more like, who are you, or laugh a lot.
