Some people don't know how to be a friend and know only drama. I'm so sorry you had to work with and deal with someone like that. I relate to your post because a year ago a work friend screwed me over. I got this lady her job and I was her biggest advocate and she really just wanted my job. My boss and I had tension because our whole department was being squeezed by higher ups. Frenemy took advantage of my weakened position. She threw me under the bus in every meeting in front of everyone. I ended up scrambling to get another job in my field. She now has my old job and I'm pretty bitter about it

My ex boss was not a nice person and neither was frenemy. Now they are besties and frankly they deserve each other. Someday that relationship will take an ugly turn and I am happy that I'm 1200miles away from it

I don't mean to make this about me. My point being that people like that make their own hell by being addicted to drama and conflict. Consider yourself free?
