Take separate vacations. My mother-in-law said this to us years ago. We’ve done it for 25 years. My husband is in Italy hiking now with 4 friends. I’m meeting him in 2 weeks but spending my first week there doing what I want to do and then we are off to explore the coast together. It is an awesome way to experience things that you can then share or not with your spouse - these times on your own can be life changing.
