Online dating can get complicated. People have expectations and size each other up on the first date. One may think it will continue; the other not! I don't date anymore, but when I was meeting men this way, it was stressful! One memorable first (and only) date from an online meeting, was at a restaurant where the guy cried over his surf and turf about his ex girlfriend leaving him. I ended the date politely, and he sent several furious emails, trying to scare me by saying he was "cutting up a body in his bathtub."
Were I in the mindset to meet men thru online dating sites, I'd be very cautious, first of all, and second, not hesitate to cut it short if you feel no chemistry! Be honest, and listen to your inner voice. Don't be pressured by the fear of disappointing or hurting someone after one date!
