It's certainly time to live in the real world, with real people, instead of someone you don't know as well as you think you do, but have put up on a pedestal.
I agree about having a party or joining a club. If ever this girl ever becomes really interested in you, you might even find that the real person, behind the dream girl you have imagined, isn't even right for you after all.
If you do get in touch, to say that you don't want things to be awkward, try to make it sound relatively casual ~ and don't let her think that you are just sitting around pining for her.
Get out and do things ~ with real people.
(That's good coming from me ~ sitting here on my computer, talking to my 'cyber-friends'!)
