Are you sending flirty texts during the day? Not blowing up her phone but just simple things like "Thinking about you, had a great time last night" "Can't get you out of my mind" "You looked great" etc. Don't try to be someone you aren't, so flirt in the way that's you.
Try it and see how she responds.

Let me give up the need to know why things happen as they do. I will never know and constant wondering is constant suffering. Caroline Myss
