That's a reasonable question; I did think about it at the early stages of the idea as well. Someone you believed was your best friend suddenly going off the rails is only one example of why you wouldn't want to be friends anymore. There's also "what do I do if we just drifted apart too far and now I don't care about their life?" or "What do I do if my best friend for life slept with my spouse?", etc. There are at least several possible ways to deal with it. Over the course of working on friends!forever, I could've never imagined I'd make the decisions I did and add the features I did. Yet now they seem vital and even more important than some of the original ideas I put into it. At least for now, I believe that it's best to let the concept progress naturally and make decisions about how to handle situations like that when there are more people actively using the platform.
