I like these words by Osho:
Love relates, but it is not a relationship. A relationship is something finished. A relationship is a noun; the full stop has come, the honeymoon is over. Now there is no joy, no enthusiasm, now all is finished. You can carry on with it, just to keep your promises. To do so is comfortable, convenient, and cosy. Perhaps you do it because there is nothing else to do. Perhaps you think that if you disrupt it, it is going to create much trouble for you… Relationship means something complete, finished, and closed.
