Never ever forget this important rule, rule #8. There are sound and logical reasons to break up. And in fact, more breakups have to occur than not. That's the evolution of finding a mate, and you have to be willing to dump a lot of folks before finding that right one. If you're not good at dumping people on their arses, it stands to reason that you will hold on to losers and live a substandard life. Your choice...be content and happy or be miserable and always wondering "what if"...
