People change over time and that’s normal. I don’t think you have to do anything. When there’s a significant shared history and foundation there, you never know when you might look back on that and think differently than you do now. My childhood best friend and I were so close, then drifted apart, and now I’m so grateful to be close again and have so many shared experiences that we can laugh about. There’s nothing wrong with space but I don’t think going out of your way to “end” it is necessary. My two cents for what they’re worth;)
