What will you do when the person that you leave behind comes back to your life but she's different now.

Oh let me rephrase that...that she is different from YOU now.

The things that she does to you before are the things that she's doing now to other people.

Would you feel hurt?

Feel betrayed?

Jealous?

Do you feel the absence of being special to her? 

But what is your right to feel all of that when you are the one who leaves her behind?

When you are the reason for her pains.

When you promise to her the world but in the end, you just left her?

Can you blame her if she wanted to forget all her feelings for you?

That she wanted to forget you?

But in the end, she can't do that because after all the pain that you brought to her you are still the one that she all ever wanted.
