Dark side of loving you

I've never been here before— I gave you all my heart, but you never gave me yours. I trusted you fully, but you were never faithful. I gave you my fragile heart, and you broke it into pieces. Is this the dark side of loving you? Is this the dark side of trusting you? You never saw the worth in me— late replies, arguments that never ended, all the blame fell on me. You never saw a glimpse of us. You never felt my touch. I never knew loving you would leave me in the dark. Is this the dark side of loving you?
