Has anybody actually ever had a successful “break” in a relationship?

I’m of the belief that breaks are just an excuse to explore other people and other options without guilt. I think that if you’re going to take a break, you mine as well break up. Personally, I’ve never even heard of a successful “break” that ended up for the better and didn’t cause a complete implosion of a relationship. I’m just curious if anybody has actually found success in that…?
