I'm 22. I have 6 ex girlfriends, and a lot more girls that were not a proper relationship, but for the sake of argument here, we'll call them exes.<p>I deal with this problem simply. I delete them and remove them from my life. There have been no exceptions.<p>I've run into one or two of them around town, said hello, and went my own way.<p>It can be done, oddly enough. But then, I don't ascribe any meaning to deleting someone from Facebook. I have 100 people in my friends list, and I'd invite every one of them to a party.
