Very good, but it would be more haunting if you didn't write that she liked him sober. That gave everything away, and let us know exactly what was happening. I gasped a bit when I put it together, and realized that this man was her husband, and he was Colin. By using the next line to point it out, it ruins it, and leaves less to the reader's imagination. But it was great, and very well written. Great job! This story deserves more attention than it's getting.

PS That was really skillful, seriously, how we had to slowly figure out that the man was Collin. Very gripping.
