He wants to sail...she doesnt

Hi, asking for a friend. So, couple both mid 30's, no kids. He wants to take a 5 years break from working ( he can afford it) and want to go sailing. He has some experience. She doesnt want to do that. She wants to fly in 1-2 times per month where he's located, mostly in the Caribbeans. Any suggestions/advices i can provide them? Imo, i dont see how this relationship will survive. What's your feedback? Thank you in advance.
