在我有生之年，有多少次我试图将真相告诉你，但是我太担心了，就没那样做，因为我向你发过誓绝不对你撒谎。

I tried to tell you the truth many times in my life, but I was too afraid to do that, as I have promised not to lie to you for anything.

你已经发过誓，你不能退却了。

You have taken the vows; you cannot recede.

我是发过誓，我也让你失望了，我对不住你。

I did promise, and I did let you down. I'm sorry.
