How can you "fancy" somebody you have never met? Sounds to me like you fancy the idea of her. projection, as the psychs call it. You might meet her and find that she doesn't do very much for you in the flesh, or that she picks her nose, and (maybe this isn't such a clincher for an American ) have you ever heard a Brummie speak?
On the other hand, she might be gorgeous, intelligent, fit as a fiddle, and find the Mass. accent deeply sexy...
I'm with Contrex on this one. I think at most, you fancy the idea of her just now. Especially since you give no indication that she has the faintest idea that you do, nor that she's given any hint of reciprocal "fanciness" (yeah, just made that up, I think
).
Why not just take your trip as planned and see how things go. She might be your dream girl and the two of your hit it off and become soul mates.
But that's a lot of pressure when you haven't even embarked on so much as a long distance relationship. I know, I know. Your heart goes pitter patter whenever you think of her. But for all intents and purposes, she's not even real.
ETA: Speaking as a girl, on the rare occassion when I've found myself in a situation where a guy professed fancying immediately upon our first face-to-face meeting, I ran! It excelerated the one-sided "relationship" to the status of him being a stalker and I always wondered where he got the notion that...well, you know what I mean.
