Betrayed, probably not, of which I am very grateful. But I have had a couple of friendships that went bad. We did not become enemies, but we have stopped communicating. I hold no grudges. We just went our separate roads.
I have been betrayed by one of my "best friends". She just went away without any explanations. Our friendship died a slow and painful death. I have forgiven her some what but I'd never forget it.
Once a friend of mine, hijacked a situation between me and my gf and finally after a few days, my gf started dating him. She was behaving completely behaving differently to me after that incident. I hate that guy.
