It is ok, mate, don't worry.
One of the reasons I was so dismissive is that I used to work on ships for many years and believe me passenger-crew relationships don't work.
Crew-crew, yes, I have seen a few marriages in the past. And as I keep in touch from time to time, they seem to be getting on, albeit on land....
Passenger-passenger... I witnessed many getting together, but I cannot say wether the unions lasted or not.
The crew member will always want to go back to sea, one way or the other, it is not just the money, it is the traveling the world, it is the way of life, the camaraderie, the berd pulling on board, the craic.........
My ex hated it.
I wish the lady all the best of luck in the world, but in my sincerest opinion, she is wasting her time.
