You will get there, CG, in time! You are thoughtful, smart, look great in yellow... that's going to match just right with someone!
Just remember that a second date is a commitment to nothing more than a second date. And it's ok to pay attention to the "red flags" to some extent, you will often be right. I try to remember that on the first meeting we are both really nervous, whether it's showing or not. But if you decide to just enjoy that moment, not worrying about what it all means, I find you can usually get past that.
