This answer is so refreshing to me. So many times these threads about lost relationships are filled with people who aren't at fault. I get it, sometimes it really is the other person's fault and maybe those answers are easier to relate to. Even people who are at fault can relate because often times they don't see it as their fault.

Most of the time people do just grow apart and change. That's fine. I have two people who were very close friends that I no longer really talk to that when people ask why we haven't talked much I just say "oh you know, different cities, we grew apart" so on and so forth. But in reality I know one of them was way more of a 50/50 split over stupid shit we both did and the other one was largely my fault and we didn't just "grow apart". I made it happen, but also at first I blamed them and it took me a bit of time to realize all the reasons I put on them were more like deflections and excuses. People need to just be real with themselves and at least entertain the idea that maybe they share part of the burden. It's not always a pleasant thought exercise, but it can also lead to rebuilding bridges. Maybe your relationship won't be the same as it was, but at least you can still have a relationship with that person instead of talking shit about them on the internet.
