Breaking up is hard to do, especially when you're the one doing it, so finding a way to let him down easy is a must. But is that even possible? Since you obviously cared about this person at one point, sparing him any embarrassment is crucial. At the same time, it's important to be firm, and make it clear that you no longer want to be in the relationship. I don't know the answer to this one, so do tell, what's the best way to break up with someone?
