I have no idea where most of my old flames are, and that's ok with me, too much energy would be needed to track them down, and for what? But none of those relationships ended badly, we just mostly continued to grow in different directions. One who was a great friend but not so great a boyfriend I still see, as I managed to transfer them to one of my close cousins - now we're related and easily stay in touch. He's much better in the "cousin" role, lol.
