I prefer spending some actual quality of time (having a walk, having a conversation) with my SO instead of staying idly next to my SO and half consider it couples time.
If you share an interest then go for it. What I meant is that some folks prefer to prioritize watching something "meh" on TV with the excuse of spending time with your SO and then complain they don't have time for gaming.
Instead of half assing two things: free time and familiar time. Spend some free time on your personal interests and then spend time with you SO where you are both engaged with each other!
