You're a troll. There is no way that you can be that thick. Absolutely no way. You think she'll love you if you put that you're in a relationship with her on FB, are you truly mental or are you just fucking with us? You gotta be just fucking with us, there is just no way you can be dead serious about this shit.
Lol at you pretending like you aren't talking about your ex in the OP lol you might as well say it instead of saying "if a girl adds you on FB does that mean she wants to fuck?"
And to answer your question truthfully, no, don't do any of that and stop obsessing over one cunt.
