Our Cruise Dream Is Now Shattered

My husband and will both receive our state pension next year. We always promised that we would go on a world cruise when we retired. However, after Covid, my husband has changed his mind, saying it is too dangerous and he can’t understand anyone who would. I’m so disappointed as I was really looking forward to this. This is causing so many problems between us and we’re doing nothing but argue. It’s even casting a shadow over our retirement as I feel so let down. Do you have any advice?
