How Can You Hurt Me When I Don't Fight Back?

I hear you yell and criticize me,
I don't fight back, why can't you see,
I care too much to hurt you like that.
How can you say these things just like that?
I've always been there for you.
I don't know what more can I do?
My friends say to move on, I think it's smart
But what about the missing piece of my heart,
I guess I'll move on, I still care about you.
I always will care, no matter what you do.
