I will never say that I didn't need you.

I will never say that you were bad.

I will never say that I felt alone when I was with you.

I will never say that you didn't change me.

I will never say this, because these things are all lies. 

It is a lie to say that I don't need you, because there is a constant hole in my heart

You did treat me poorly. Some of your actions were inexcusable. But you aren't a bad person.

I felt so lonely when I was with you. I will never say that because it's not fully true.

 You changed me. For better, for worse, I don't know, but I am changed.

These are lies that have been told to me about you.

But here is one truth I have been told about you.

You weren't strong enough.
