Married 4 decades + to the same woman! At first, she climbed a bit, even some alpine stuff in the Pacific NW and S. Teton, descending from the summit in a T-storm. After 2 years, (she loves to tell this story) we were dining out in a restaurant at the Gunks (probably The Mountain Brauhaus) and I said " this fall we'll work on raising your rock climbing standard", to which she replied " Jeff, I don't have a standard and I've decided rock climbing isn't my thing!" I stammered something, then she said "don't worry, I know you love it and I won't ask you to stop."
As any couple does, we've had some rough patches and I've had to throttle back a few times, but I've spent a lot of time in the Alps, all over the American West, Canadian Rockies, Britain (Wales, England, Scotland) , Greece, and am still climbing and guiding 70-80 days /year, so life is good. Fortunately, she loves travel, foreign or domestic, so she has accompanied me on most of my longer trips.
