This is my characters Gabriel Nights and his partner Heather Tanner. Because of what he was he never really could tell her the full truth, for fear he'd screw things up, or drive her mad. And she not able to fully trust him because he was keeping things from her, was not able to fully commit to him either.
It was a bitter sweet romance that ended tragically when she was torn to shreds by a serial killer 3 years later.
