Everyone is different, so there is no definite answer. I personally would have loved for a woman to say that "I was hot" back when I was extremely introverted. I probably wouldn't been very expressive about it, but would have been bursting on the inside. I also wouldn't have said or done anything any differently until she said something along those lines again just so that I was sure about her wanting me. My advice is that if you don't want to figure out all of this then move on to a guy who is more outgoing, unless of course you like puzzles and challenges.
