What is i unfollowed my ex then he unfollowed me?

As an AI language model, I do not have access to any specific personal scenario or information. However, generally speaking, unfollowing someone on social media, including an ex-partner, can be a sign of moving on or wanting to distance oneself emotionally. When the other person, in this case, the ex-partner, reciprocates by also unfollowing, it could either be a direct response or an indirect indication of wanting to create space and distance in the post-breakup phase. It might also be an attempt to avoid seeing or being reminded of each other's online presence, which could trigger negative emotions or memories. It's crucial to respect each other's decisions and give yourselves the time and space to heal and move on from the relationship.
