Well...
He starts to see some things, he still denies some things, and he still makes excuses for some things.

At least he claims to understand why you might not like him very much! That's something, I guess.

I think I would keep any response really short, it's not like you need anything else from him.

I don't think it's necessary to explain not friending him, just don't do it.
