Hey dude, great entry. First, don't worry about the DDR stuff. You're out, it's social, not a big deal. The main thing I'd encourage you is next time, instead of texting the girl to see if it's her, just go up and talk to her. You were a bit too passive in this situation, "texting" and then telling her to come see you "if she has time." Step into your role as a leader, go talk to her if you want to talk to her.
