Friendship too ahh ahh

So i met this best best friend of mine 3 years ago and i broke my friendship today for a personal reason that I'll only share here soooo the reason was look I've known that guy for 4 years and i think people change alot from puberty because he changed very much so after we came to highschool my guy and me found a new friend it was normal just a normal friend but overtime he got a really good friend and we became a trio so after 3 years also now i finally left the trio because i think no not only think i feel like I'm getting less attention and I'm just backup for the two of them my best friend just didn't feel like a best friend so i really thought about this much but i feel like it's not a best friend friendship anymore before that other guy came i shared everything to him we were really close but after 2 years with him it all changed he started to just do more things with him than with me and yk ppl change and people have feeling like jealousy so i was jealous i guess, because idk ... So now i like left the trio they're duo and I'll say i only want one best friend that i wont ever get I'd rather be alone now because there's not many ppl that actually are good ppl man i hate this man bro so now do you rhink i did the right choice because i really think i did

Thanks for reading this._. and please tell me
