Does acting psycho with a loser get rid of him without hurting his feelings? If so, who would have all the time and the patience to do that for someone they want to get rid off?

I have this friend who isn’t weird at all (OK maybe a wee bit), in fact she’s really intelligent and pretty; not to mention, she’s very friendly and sympathetic. For some reason all the cool guys are always shy around her and the only ones that have the confidence to approach her are losers. Now, she has this really strange way of getting rid of them without hurting their feelings, she uses this reverse psychology of pretending to really fall for them in a psycho way but eventually ends up confusing and smothering them and they actually move on and stop calling her. What gets me is, is this girl really psycho or has she got a point?
