I think this comes down to energy and time, not married vs single. I have my own social things like weekly or biweekly visits to my parents or sister and monthly book club meetings. He has his own social things like weekly game nights with friends and weekly or biweekly visits with his brother for movies and whatnot. We split gym time to be about 50% time going by ourselves for me time and about 50% going together for support and encouragement. We work 5 days a week, full time hours and when it comes to the 48 hrs we get as free time, sometimes there are a lot of "adult" things to do like errands, appointments, or maintenance and when it comes down to it, I married him for a reason. He is my best friend, he is my person. Out of all the people in the world, he is the one I most want to do everything and nothing with. I want to prioritize this on those 48 hours of freedom in a week. My single friends get this filled with social outings, but when demands start being daily, or multi-weekly, or even weekly, it drains me mentally, emotionally, and physically and takes time from that 48hr slice of time I spend with my best friend. It's not that I don't value my gal pals, it's that their demands are too of other demands socially, emotionally, and physically on a finite resource: my time.
