I don't want to forgive my friend
What happened? What did he do wrong?
He blames me for everything.
It's expected that you accept their apology eventually. I know he blames you for everything, but you should try to accept his apology if it's sincere.
I forgive my friend. I know I was in the wrong for everything and I'm sorry for blaming him for everything.
I feel like you're going into the realization that you're actually the one that blames him for everything and I am glad that you are slowly accepting your flaws. I do hope you keep your friendship with him as we grow older it's more important to hold friendships as long as we can.
