Wow, if looks could kill I would be dead. But like a duck, the projected anger and hurt rolled right off my back. A few years ago the same situation would have played out quite differently.
Life has a way of changing a person. For most I think personal growth is a gradual process. For me, the process was a radical redirect that has left some people in my life confused and unhappy. Call it what you will; aging, taking stock of ones life, or adopting a more tranquil lifestyle. I simply call it self-nurturing. In some cases distancing myself from negative, judgmental people could be more accurately described as self-preservation.
Whatever label you choose to apply, it all boils down to one thing, putting oneself first. And despite the occasional blowback, for me this has been a positive life changing experience.
