I've only got what you've said here, so maybe there's another side where she's studying her butt off and keeping the house clean and you were throwing clothes and dishes everywhere like confetti, but a 6-hour argument? I can't think of anything I could care enough about to have a 6-hour argument about it. Hell, I'm not sure I've ever made it more than an hour. At some point, it's just not going anywhere, so I go to another room or something to be pissed off somewhere else. It sounds like the situation wasn't working for her at all and it's for the best that it's over. Either she's overreacting or living with you was just impossible. Sometimes two people just don't mesh and it's not worth forcing it.
