Why would you care if people stopped talking to you?
I'd rather know up front that someone was not my friend rather than to have them smile in face and spewing out false assurances we're in harmony.
Life is a (personal) journey.
What other people think of you does not matter nearly as much as what you think of yourself. Thankfully there are over 7 Billion people on the planet. Odds are in your favor you can have all the sincere friends you want.
The world may not owe you anything but (you) owe yourself the world!
Do your best to have the best!
