我将如何知道，如果我让你离开？

How will I know, if I let you go?

youdao

我离开了，但这是你让我这么做的。如果你认错的话我会很高兴。

I left, but you told me to. I'd appreciate it if you'd cop to that.

《柯林斯英汉双解大词典》

我什么也不能做直到我说服了詹姆斯让我去救你我发誓如果我成功了我一定想办法让你离开那儿。

There was nothing I could do until I convinced James to let me go to get you and I promised that if it was the last thing I did, I'd get you out of there.

youdao

If I want to persuade you that I love you, would never leave you, you can trust me with everything, it may be a superb tactic for me to believe it.

如果我想让你相信我爱你，永远都不离开你，你什么都可以信任我，或许最好的策略便是我自己对此深信不疑。
