Motts, what do you mean by some people being good at managing people? Also, how can you tell for sure when the other person isn't interested in an authentic connection? I think that I have met a few people like that and only realized what they were like after I invested a lot of time and energy in a fake friendship.

At the O.P, sorry to hear about your friendship ending. She sounded toxic, so it was for the best that you ended the friendship.
