Actually he already shown signs of letting neria go after knowing she likes nero, his friend whom he trust.
But then nero said something out of line hurting neria who selflessly only wants to care about him even when she's already reject, and not even asking for anything in return.
Nero deserves someones slap. He didn't end his friendship with nero. He just gave him a slap of reality of how he starts to treat others

I'm actuallt more frustrated with the friend
He says he never once thought he was different from them, they just picked the short end of the stick.... Okay, thats cool, but he's still not a good friend
Like, im glad he didnt one-sidedly beat nero bloody, but he still tried to pick a physical fight and all that shit-
I guess what im saying is
He picked the side of the girl he liked, and kind of turned into nero's enemy, but he should've remained friends with both, imo
We dont need the whole world turning against our pissed off hedgehog
