If you are hanging out with someone because of their connections and not their personality, don't beat yourself up about it: just change it. You are wasting their valuable time and your own by continuing a false friendship. And whatever you gain from it: a job connection, a date with a cutie, or something else: will be tainted by the fact that you faked something to get it. It's not too late to get out of this without making anyone mad. Always be true to yourself.
