Fighting For Her Love

I once loved a boy. He looked after me, loved me. Even took my virginity. But he left and let me fend for myself and my brother.
I still think about him, wondering if he ever lived his dreams. But I've moved on, started dating. Dating a man who is now my brother's MMA coach. It's there I run into HIM, though I don't recognize him. He recognizes me and when I don't fall at his feet, he makes it known that I belong to him.
Kingston says otherwise. He's a good man, but at the end of the day am I looking at this with stars in my eyes or with my heart?
