"Taking A Break" is the classic escapist cliché.
People with under-developed social skills or lack of problem solving abilities use this as a cop out
In the minds of women this is often viewed as a nicer way of dumping
a guy, most men who are not completely socially inept understands this, and realize taking a break will never bring you closer together. Only fill you with false hopes of extending the (un)natural life of a realtionship.
I your ex uses this, they're an escapist bitch and probably not someone you'd ultimatly be happy with anyway. These are people not worth your thought and emotions, you're best bet to feeling better is to realize that, and move on.
