I told a story/joke about a stalker-like person to a girl i like, but i think the way i told it made it seem like i was that person. Assuming i CANT simply explain this to her, how i make things right?
Don't bring it up again, or that subject. In fact, avoid heavy subjects like that until you really get to know a girl and are sure she'll be comfortable about it.
dont be too worried just dont actually stalk her. give her a little space dont annoy her but call her evrery once and a while and ask her how shes doing or if she wants to hang out you just need to be confident i learned that the hard way.
