hey ov, I think sending flowers/showing up on her doorstep
is a bit too much and she will most probably freak out and
get a restraining order against you.

So, stalk her. Wait outside her house and when she comes out
'accidentally' bump into her, and act surprised. Invite her for a coffee - get her
number/email if going out isn't possible.
This might end up with you succeeding or being noticed and ending up in jail.

Well, thats the best I could come up with
