What I'm Afraid Of

I'm afraid of letting someone in
afraid of needing someone again
every time I've fallen in love
they've ripped me apart
I gave them my heart
whole and beating, how could I have been so naive so trusting?
they never really loved me
all they wanted was me on my knees
just wanted full control of me
but my will's a fire
that they couldn't put out
I tried so hard to make them want to stay
but everyone of them walked away
but I wouldn't bend so they just broke what they could
I let them in one at a time
again and again they all broke my heart
so if you want to know what I'm afraid of  
I'll tell you it's that thing called love
