“What are the rules- how long should you stay in a relationship with someone whom you don't think is quite The One? Even if you know there are things you like about them (and things that infuriate you about them), how long should you give it? Is it better to be single and waiting patiently for Mr Right, or to stay with someone because they make you laugh, because you're having fun with them, and you're still young? And anyway, aren't all relationships basically killing time until something better comes along?”
