Yes, it's for you

You tell me I’m liar
You tell me I’m a full
But when you need me
I’m always following you
And now I’m alone
But I don’t need you
Because you heart me
And let me be a part of you
So baby , baby you always had my back
You were my best friend, until yesterday
Because you let me alone
With all the guys and girls
And now I know that I’m alone
But every step I’m taking
I’m being strong
Than now I know
I never can trust in you
