When she was asking the questions about your date, your shirt, etc., what kind of "tone" did she use? You did very well with things until you saw her flirting.

Could have been reworded better so that it doesn't make you look weak or whiney. Something that directs the light on her inappropriate behavior instead of your insecurity. It may have been a "respect" thing you wanted from her...but it depends how she took the message.
She might have reacted out of her own jealously toward you. But both of you are showing it.
Did you talk to anyone else at the practice or just her?
It is not about what you feel should work in your M. It is about doing the work that gets the right results. Do what works!
