I don't know if a particular attraction goes away or not. If I were you, however, I'd take what she said as a red flag b/c it sounds as if she is hinting that she wants changes made in you. Not a good thing when you've only had a few dates together.
Don't try to be anyone that you truly aren't. Maybe this girl just needs to mature a bit. Either that or she's never had her heart broken over a "dangerous" man.
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!
