Are there any other young women out there that aren't self-obsessed?

Okay I don't mean to bash anyone or women specifically but this has been an increasing problem for sometime now. Unfortunately most of my girlfriends are away at uni so I basically only see them 3 times in the year (holidays, spring time and the summertime) so I've had to resort to meeting newer girls to befriend and whatnot. The problem I find over and over again is for some reason I seem to be attracting young women who are near my age (19) or even a couple of years older who seem very self-obsessed, insecure, dramatic, and lack any real substance. By self-obsessed I mean they refuse to have a two way conversation, they ignore the other persons view points, only talk about themselves, anytime the convo starts off being open ended they end it into some boring dialogue of monotony revolving around themselves. By insecure I mean they deliberately say and behave in unnecessary ways towards others usually out of insecurity for example (wow she is so fat I bet her boyfriend would like me waaaay more) or suddenly deciding to not be friends with someone who is honest with them, and by lack of substance I mean they don't want to engage in any conversation that is open ended, conversations that are not about other people. I'm trying to understand why I am attracting women like this when I normally don't and these types do not usually make up my social circle. What am I doing wrong? I usually sever ties with them after realizing this which usually is within a few days to a week lol.
