There's a reason why you shouldn't mix business with pleasure. There's a remarkable maturity difference between you too. There's nothing that can take your mind off the old crush like a new girlfriend can!
You'd be getting yourself into a whole lot of nonsense. Play and banter with this one, it's good practice, and she could be a good friend or wing-woman, but don't take her seriously unless she takes you seriously first.
