Prove that you love me

Just prove that you love me!
I don't believe you anymore,
my heart is closed now and only you have the real key.

You've hurt me with all your lies,
my trust is gone.
I don't wanna live without you,
I love you, but I have to go on!

I'm not myself anymore,
you're in my head and all I do is starring at the wall..
So just say it, just say that you really love me!
I don't wanna lose you, cause you're my all.
