Breaking up using a celphone/SMS only shows how irresponsible and narrow minded you are. Break up is not something that you just say, it's something that BOTH of you should talk about. Don't run away from it instead both of you should face your problems, talk it all out and if nothing really works out then BOTH of you should decide if you continue or not. Pride is the most common reason for breaking up using SMS. You just want to TELL the other person and you don't want to LISTEN. I'll quit using this site if i'm wrong.
