请英语高手翻译几句话

都这样写了，你要是还不相信我对你的心，还是要在中途离开，那么，我不会挽留。我觉得已经够了，这承诺比挽留更是我的真心。

 

All this writing, if you do not trust my heart, or to leave in the middle, then I will not stay. I think that is enough, it promises to retain more than my heart.

I have already written like that. If you still can't believe me who treats you truly and insist on leaving on the way, I won't persuade you to stay. I think that is enough. The promise that is from my heart is better than persuading you to stay.
