Update to "My best friend keeps breaking my heart."

So this is an update to my previous post. For added context I'm 18m she's 18f

After reading the non troll comments I decided to cut ties. Not fully, I wanted to at least be respectful. So A couple days a ago was her birthday and I wished her a happy birthday. She said thanks and then the next day I said I'd like to distance myself from you for a bit. They were confused but didn't fight back. In the past days I've felt much better. I've been hanging out with my real friends more often now. As this is our last year of high school I decided to focus on my friends, work, and collage plans. Tonight I'm having a sleep over with a friend tonight.

So far I feel over it. I feel better both having closer and being the one who left not the the one who was left.

Tldr: I cut ties with a bad friend in a respectful way, now I'm chillin
