Friendship Break ups

A few months ago i lost one of my best friends. For multiple reasons, a lot of it at surface level was my fault.  Over the past few months i have realized that it's better this way. I mean it does complicate things with our mutual best friends but it it's better. I've realized that even when i thought that it was a healthy friendship it wasn't, weather it be slight comments she had made in passing or straight up lying to me. It wa all very toxic, now don't get me wrong. The reason our friendship ended when it did was on me, i made some stupid decisions. While i was going through a lot at the time, i still was being a shitty friend. But after realizing that our friendship was in fact toxic, i realized that it was gonna end no matter what. I'm just thankful that we were friends for as long as we were. I don't think she feels the same, she unfollowed all of my socials, and deleted any content with me in it. I get it, she wants a fresh start. I just hope that in 10 years she can look back on our friendship, and instead of remembering the sour way it ended, she can remember all the best parts. Not everyone is meant to stay friends forever, i just think it's important that you learn something from each decaying friendship and that you are thankful for the time that you had together.
