I think she can't have it both ways...she can't tell you that you are only friends but still desires you to court her and flirt. It comes down to whether you can remain friends with her while she is dating someone else but also maintain a boundary of friendship and not court her and flirt with her. It is all about what you can do...if you feel flirting keeps you in the running, then I support that, but protect yourself as well because there is no way to know how it will all play out.
Let me know your thoughts.
