I have a date with this girl who has a bf. I don't think she is aware that I know this fact. She is also quite flirty and has canceled on me once before. One thing I have noticed about her is that she is shy and insecure if you can push her buttons, so I'll try doing that. This is my second and last chance I'm giving her if she decides to flake. Do you guys have any tips on how I should act to her and things to watch out for? We are going to a pool hall and possibly dinner after depending on if pool goes well or not.
