If you've said some things to her in the past that was not nice, How would you become friends? If I call her up, what should I tell her?
I've already said i was sorry multiple times, via fb. Should I tell her i'm sorry and that I didn't mean it? or should I deny that the facebook account is mine?
She is probably positive the account is mine, but she has not legitmate proof to say this. i.e no technical proof to link the account to me.
