Rationally - I know he gave me his card, but now I'm thinking that he must speak to interesting people every day and for me it was rare. It was just a business card with nothing personal scribbled on it. I emailed him and it was just friendly and chatty but it was a bit too long. Even if he does reply I just feel that I put myself out there for a rejection and I think that I need to know how people shrug over these things?!
I know if the situation was reversed, I'd feel flattered, a little awkward for a short while but not that much more. I certainly wouldn't think 'what a foolish woman to think well of ME'. So.... why do I feel so stupid?
I had met a few people on line and felt no chemistry and the chat was difficult, so perhaps I was in that mode, and I met this guy and it was so easy to talk to him and I thought it was a date. 
[hconfused] I am just so embarrassed now.
