I think I should leave it alone

I have this friend and we been friends for months now I met him in this group chat and we been friends ever since and It’s genuinely been refreshing to talk to him and he’s actually one of my favorite people I talk to (used to) on a daily basis so my bestfriend and him got into a very heated conversation and they always get into these arguments and it’s always my bestfriends fault in these arguments and I always tell her too chill tf out and one day after one very heated argument he unadded everyone in our gc and unfollowed everyone on instagram, but my bestfriend is not even in the gc at all so I’m genuinely confused to why I got unfriended, i defended him and everything. I even texted him afterwards and asked if he was okay and I got left on read, texted him few weeks later and asked him if he wanted to play. Left on read again. I genuinely think he doesn’t want to be my friend anymore and I don’t know why. We used to play the game together and have so much fun together but now it’s like he hates me and I’m so confused on why. I even bought him stuff on the game beforehand. And if he unadded me because of my friend why did he unadded everyone in the gc if she’s not in there??? I don’t know if it’s family related reasons but if it is then i understand why, but that’s why I keep contacting him to figure out but I just keep on getting left on seen. I’m not asking for reconciliation or forgiveness I just want to understand. Because i genuinely cared about him to the point I stalked his reposts where it’s sayin “I forgiven you i just don’t want reconciliation” and I don’t know how to take that. I don’t know what to do or how to move forward I just feel like I did something wrong and I’m trying to fix that, I can’t fix bridges that are already broken but I can reconstruct them :/
