If someone is actively ignoring you

And you have alot of history with them but long story short bc of a fight between mutual people he has turned his back to you without hearing your side, despite everything you two did (late calls, photos, gaming sessions, movie nights, etc) & despite having feelings for each other previously, would you type a long goodbye message or just block & move on?

I cried alot, and it took alot for me to accept my foolishness for only wanting to see the mask he wore so well. I still want to say goodbye & wish him well. Its not an attempt to reel him in, but closure that I've said everything I needed to (or maybe thats too selfish of me) but idk if that makes me look desperate after 4 previous attempts in a months span of trying to talk to him to get him to hear me out😔💔
