Ask her perhaps? But if she's avoiding you, eh, it might not be worth your time anymore.

People tend to forget, if someone really enjoys your company or likes you, they'll make the time to talk or be with ya... Makes sense, ja? We've all been there when we "bent" a little methinks.
But as the saying goes c'est la vie... Perhaps it's her loss to not getting to know you better and not walking down that road one possibility...
