Revenge sounds good, chewing him out feels amazing, squashing his tiny pride in public.would be sweet, but the best way to treat these fuckers is not even giving them the time of day.

I guarantee they will stew over you for weeks/months/years, while you move on with a spring in your step and forget what he even looked like.

Even better is deleting his contacts and when he comes crawling back you don't even know his name.

Be the grey rock. Don't give him the attention he craves. Move on and up.
