I hope this isn't taken in the wrong way but as the other poster said, you have been looking for this crew person for many months--- ships crew members meet new faces basically every week.
You're on this week, you're off next week--- next week someone else is in your old cabin, eating at the table you had, sitting on that favorite bar stool you had, talking to that favorite bartender, waiter or whomever the case may be.
Sometimes the crew members don't want to be " found ".
Not sure of the circumstances but I would give it up as experience.
