Many years later, we never ever meet again.

多年以后，从此我们后会无期。

Today I'm going to visit my relatives whom I have never, ever (and would sadly probably would never meet again in a long, long time) met before.

我们今天主要是见我的一些远房亲戚(以后能不能再见到还是一个问题)。

In life there are very rare chances that you meet the person you love and loves you in return. so once you have it, don't ever let it go, the chance might never come your way again.

生活中，遇到你爱的并且爱你的人并不容易，因而，一旦遇到了，请一定要珍惜，这样的机会不可能有第二次。
