Why would my ex block me randomly on tiktok?

Okay I know what you all are going to say “ why are you stalking his page how do you know” read this before saying anything

First off I wanna say I wasn’t stalking his page for context a year ago when we dated I used to tag him in posts on tiktok and stuff we broke up almost a year ago actually but last time we talked was on Christmas Day because he wished me merry Christmas while he had a girlfriend ( I contacted him on November he told me to leave him alone because he has someone new) I did respectfully then he came back I called him for it and we started arguring it’s a long story but he said his girlfriend was okay with him talking to me which was weird, anyways someone liked my comment I tagged him in I was curious so I clicked on my comment ( tiktok sends you a notification when someone likes your comment) then I saw his reply wasn’t there I was curious until I found out he blocked me like a week ago I knew this because 2 weeks ago someone liked another comment of me tagging him and I wasn’t blocked than I was blocked just recently which is pretty weird I post myself a lot on tiktok and changed my username like 10 times since we broke up. This is really weird what is this meaning of this?
