I think it can work when you both settle down and just be plain honest to one another. but without honesty in a relationship, how can a friendship work? but I think I can be friends with the person I breakup. just it depends on who and what occurred during the breakup. but that's just me ^^; I don't feel people should have a grudge against one another. but.. *BUT* if it causes to much suffering to oneself its best to just leave things as it is---and I guess the grudge will always be there. but it will pass as time comes ^_^
