We broke up.
We decided that we’re better off as friend (oh, seriously?).
all mean the same thing, don’t they? They just mean that your relationship with your boy/girlfriend is over; that it has been broken in one way or another; that the two, or most likely, (only) one of you got tired or maybe just bored of the other one; that one side just can’t take the relationship any further and decided to end it with whatever reasons.
Isn’t it funny how you could never start a relationship with only one person willing to take part in the relationship, but you could end it with only one person going away from the other one. Well, some people would say that one person could try to hold it back together or not letting the one one go anywhere, trying to keep the other side from slipping away, but we all know that the truth is, when one has decided to end the relationship, when one has decided to leave the relationship behind, the relationship is finished. (S)he has slipped away from your hand. Because when there is only one person in a relationship trying to keep everything in its way, while the other one is trying to get away, it is not really a boyfriend-girlfriend-kind-of-relationship anymore. It might still be a relationship, but rather it might be a someone-and-his/her-admirer-kind of-relationship, and both person in the relationship already know how it would end.
One could say whatever reasons to end a relationship, but for most of the times, it only sounded like “I just want this relationship to end” to the one who’s listening. And when you are that someone who’s listening, whether you decide to say “No way” or maybe “Okay,” deep inside, you know that everything is over.
