It always felt like starting all over and was always painful.
Once I even continued to date a girl just to avoid “starting over”.
Breaking off communication with someone I had nothing in common with, or at least who was missing qualities I was looking for, became easy.
Honestly, it was often a relief because there were more first dates waiting and I would be able to remove someone from my list of potentials.
Once I relaxed, I felt much better about the impressions I was leaving.
