Typically, don't get involved with a friend's ex. Seldom ever works out. Ever.
Yea, she wasn't right to date you when she still had feelings. I'm not sure what was going through her mind but the focus is you. Your sig says you are nearly 17, you'll be ok.
You can say goodbye to girls soon and start dating women. Women are different from girls. They're mature, they know what they want, and they'll treat you right. Watch out though, sometimes girls never grow up into women and are stuck in an immature world, you've just got to know how to wade through to find the woman for you.

This. Simply and honestly.
If she's playing you, she's not right for you. Find someone who cares about you! :)
