How I Was Supposed To Know lyrics

I want to know why I never known you. I want to know 'cause I say I know you. I want to know why I am not welcome to be with you at night. How was I supposed to know that I was on my own? Why did I keep telling you that I was on my own? Don't know But in time I'll keep all my colours warm I keep all the others warm How was I supposed to know that I was on my own? Why did I keep telling you that I was on my own?
