Should I try to reconnect with an old friend/crush after a rocky ending?

yeah go for it. whats the worst the worst that could happen? she wont add you well then screw her. but if she does, well actually you should say this through the invite. tell her that how your friendship ended was a lie, tell her you never said or did those things. if she wants to knoww more then she will add you. then send her messages eplaining all the stuff that had happened and why you didnt tell her b4 and just tell her everything, and be honest girls like that. if none of this works then shes a just a jerk anyways so who cares. hope this helps sorta though
