So in total, you work 38.5 hours a week (Assuming that you work on the weekends). That is surprisingly low considering all the hardships of being a solo founder. Kudos!
I work the occasional weekend and about 2-3 hours hours in the evening twice a week as well. I might also keep up on some support for 10 mins here and there whenever I have some downtime.
The only rule my partner and I have is to keep electronics out of the bedroom. Also, for context, we don't have kids.
