9. Know when to say good-bye. 知道怎么說再見。

While this is tough in any relationship, this can be especially hard over long distances. When communication becomes one-sided or sparse for too long and for no apparent reason, when arguments become too frequent, when the whole thing just seems like more trouble than it's worth, it's time to re-uate the relationship. You have to remember that for a healthy relationship, no matter how far or close, you must be willing to let go.
對任何類型的感情來說，分手都不好受，對異地戀來說更是這樣。當時間或說不出來的原因讓交流變成只言片語或無比罕見，當爭吵頻頻現身，當整個形勢淪為本不該成為的大累贅，那么，是時候重新審視你們的感情了。必須記住，對于健康的感情，無論咫尺或是天涯，該放手時就放手。

Long distance dating is all about a balanced relationship between partners; a relationship built on strong foundations of trust, understanding and determination to make it work. The two partners should be reasonable about their expectations and willing to cooperate so that this relationship can lead to a happy ending. If these parameters are taken care of, you have nothing to worry about.

異地戀就是情侶間達成平衡關系的一種感情；建立在信任、理解和決心基礎上的感情必將有所收獲。兩個人應當理性地對待共同的期待和意愿，共同努力，這樣這份感情就會修成正果。如果以上因素都被認真考慮過了，那么，別有什么好擔心的了。
