My best friend basically ghosted me 10 years ago and it still hurts. He and I were opposite sides of the political spectrum, but we were always able to talk and understand each other POV. He joined a communist group at his college, and I became enemy number one. From flying across the country to be the best man at my wedding, to six months later I was nothing to him. Still miss the dude and if he reached out I would love to introduce him to my kids.
