do you think it needs to be either completely like this or completely different?
maybe there is a way between the extremes. like e.g. not expecting so much from others immediately but carefully allowing a relationship to develop if it happens. it's good to know that people can be like that. still I wouldn't use the strange behavior of a few people as a model for the rest of your life.
most people change during life anyway and see things differently again and again. so it's unlikely that things are always going to be the same from now on if you don't want that.

(sorry if I'm not helpful. I don't want to interfere so much. but I had these ideas before. so I thought I write what I think about it when I'm more optimistic.)
