if someone had their Final Fantasy XI character as "Iloveandrew", then yes I would feel a little creeped out and would probably get a restraining order, if that's what you're asking. That is not "unconsciously" showing your affection, that is just creepy.

She will feel uncomfortable for awhile. I suggest telling her that you're sorry and after that, give her space.

Coming from the other end of the spectrum, do you know how hard it is to meet other people when you have a stalker on your hands, blowing up your texting inbox or your facebook wall? I've had a girl do that to me over the past 2 months, and it has been pure hell. The only way I could get rid of her was by completely ignoring her. I felt bad, but even if I gave her the time of day, she instantly wanted to sex me, which is wrong. She needed her time to mature and figure out things. So do you.
