I don't agree with you. There is no good way to break up with someone. If you do it to their face they feel like total shit and you feel like total shit. Also it can be dragged out...and really...you can't collect your thoughts properly if someone just told you to your face they are dumping you. Maybe if you have been going out a long time you owe them a break-up that is really annoying for you and doesn't help them at all either. Of course I am speaking from experience. The one time I was dumped the girl did it over the phone after she and been avoiding me for a week. I don't think it would have been any better or worse in person or over the computer. I broke up with a girl one time by just not returning her calls - but we had only known each other for a month and it was a weird situation where a girl I was in love with before I met the girl I dumped came back from China (my current girlfriend). I know, I'm an asshole, but I am telling you that no one thinks after a break-up "Damn, that was a real good way of telling me I have no meaning in their life"
Oh, i know that feeling, i have yelled at my cat, only to find myself spending the next 1/2 hour telling him, "you're a good boy".
