Was on dating sites since summer to finally meet someone I really like. But... I felt EXACTLY what you are now, many times over..... Until you actually meet up. Both the girl I met and myself were pissed and tired of meeting up with people WHO LOOK NOTHING like their profile pics...
One day, chatted with a rather sexy lady.... All is lookin' good, we have a date set up for the next day. Then right before bed, she sends me a pic of her that look absolutely NOTHING like her profile pics. Odd feelin' to go to bed replying bullshit (didn't want to say what I thought right then) but when I woke up told her "you can't be mad at me for canceling tonight as you look nothing like your profile pics"
Anyway, best of luck to you, she seems hot for sure. Until you taste and smell the person, nothing is set.
