I'm not sure if they still do this, but I know of a few instances where they would let guys off the ship early to take care of personal matters. Especially if your ship is planning on a tiger cruise, they used to welcome the open racks. The chaplain might be able to help in this regard as well.
Here's an idea. When you get home, send her some flowers (they don't have to be roses) with a note inviting her to a public place for breakfast, lunch, dinner, coffee, dessert, whatever you like. Something like " I would love it if you would meet me at 4:00 for lunch so we can talk". Phrase it however you like, but it puts the ball in her court and you are making an honest effort to communicate with her.
Good Luck.
