If she has a boyfriend, move on. Aside from the rudeness of trying to intrude upon an established relationship, on a practical level it can be harmful to your health.
Keep looking, and remember that a 90% failure rate (not always rejection -- failure in the sense that they have a boyfriend or other pursuit, etc) is probably going to be par for the course. Make your peace with that and be appreciative of every honest possibility you have for a good relationship.
And I'd advise against ever again looking someone up online for background info. Aside from the creeptastic feel that sort of thing has, you will never hone your people-sense that way. Just be open to what tomorrow holds, let go of the desire to control how things pan out, and when you hear "no thanks" keep those feet moving.
