This sounds like a man who got angry during an argument and hit his girl and then feels incredibly guilty afterwards.
"i'm ashamed of how angry i got.."
"when i summon a duel.."
"i know you got the beating.."
"lovers may quarrel and spar.."
"i know i fucked up ... (ad infinitum)
"don't tell your friends about me"
it seems like he's feeling guilty and embarrassed that he resorted to physical violence and he is apologizing between making excuses and is ultimately concerned about how their friends will view him if they found out.
