Personally, I don’t have many past relationships that I am interested in rekindling or maintaining. I have a small group of close friends, a larger group of not as close friends, and my family. Beyond that I have work acquaintances, but those are people you’re sort of forced to see and spend time with. We meet lots of people over the course of our lives. Some are there to stay, and others aren’t. Maybe you no longer have the same interests or worldviews. Maybe someone had a kid or got involved with a partner that took all of their attention. Are these people you genuinely want to reconnect with, or do you feel obligated to check in because of your history with them? In any case, it’s probably worth remembering that your brain can only handle so many relationships. In my case, I’ve found my relationship comfort zone and am very happy to have the people in my life that I do, and don’t feel a need to search for more.
