Distancing yourself from people is only a vicious cycle. Your expectations go up; your friends are less inclined to fulfil those expectations, because it seems like you don't care anyway; when your expectations are not met, you distance yourself even more and try to convince yourself that you "really don't care".

Also, what gives me the right to have such high expectations of people? It makes me seem like I think I'm perfect.

Harsh words from a close friend, and I thought I'd jot just a few of them down here so I wouldn't forget.
