I've had similar experiences as Boopers. It is in our good nature to think that the snub has to do with something we have done or who we are, but the reality is, the snub is the problem of the person doing the snubbing. For whatever cause or reason, the snubber is using the cold shoulder technique to keep people away from them. It could be to hide a prejudice, not make committments, because they are very insecure, because they want to control and punish, or even because something in you is what is in them and they don't want to face it. I feel sorry for people who play that card.
