Well, you know her best (in fact none of us even know who she is, so...), but I just want to warn you about something else.
Are you sure she's sending you subtle hints, or is she just acting the wa she is and you see some hints, because you wanna see them? Answer that for yourself.
I'll just repeat to what I said in the PM:
Let your heart decide what to do and your brain how to do it. Good luck!
