I think what goes on in your opponent's mind is "now that he has beaten me, he wants to keep winning by beating me again and again".
I usually do not rematch no matter whether i lose or win and about good manners I don't think it has anything to do with playing. Just the usual game etiquettes are enough. In fact even if you don't chat it's totally fine.

Why do people ask for a rematch immediately after winning a game? I thought it was good manners to ask for rematch, so I offered rematch immediately after checkmating my opponent, but my opponent insulted me with bad words. What did I do wrong?
