I didn't know how to behave

I didn't know how to behave,
whether I was the master or the slave.
I tried so hard to close my heart,
and just waited for you to show your last card.

I couldn't trust you even though I know what you feel.
I didn't dare to; I hid my soul behind a seal.
I was afraid to dream, to feel, to hope,
so much that I doubted I would be able to cope.

But no matter how hard I fought,
I couldn't keep running and found myself caught.
So now I think I just give in and surrender;
my life, my soul, my heart, they're yours to put in love's blender.
