something told to me

I have liked you for so long,
In a way so very different,
And only felt towards you.
My wall is high, my guard is strong,
You don't break the wall,
You simply break me.
I cannot walk away,
The invisible cord is wrapped so tight.
I would give the world to be let go,
I would give the world for you to bring me in.
I would give you the world, if you would let me.

How do you respond, when this is told to you?
How do you respond when the guard is down and vulnerability is clearly visible?
What do you say? How do you answer? It's something told to me, yet I do not know how to respond.
