look me in the eye and say the 3 words that I've longed to hear

You know I won't do such things to you ever again.

And today I realized that I have broken it before and now, it is hard to have it back.

But I know you would try.

I too know that apologising won't help.

But I've changed,

And it is you, who have changed me.

So, will you give me one more chance to prove to you that I am true?

I am not her.
I am different.
Sorry is not the hardest word.
Meaning it is the difficult one.
