We do:
Mon - my sport
Tue - his sport
Wed - my sport
Thurs - none
Fri - his sport (summer only)
Sat - none
Sun - his, finished by 1 and will give it a miss if we want a whole day out, but that's unlikely as both DCs do sports in the afternoon anyway.
However, we will both give up ours if the other or a DC has a more pressing commitment that clashes (the DCs do a lot of sports/hobbies too). And we are all home by 9 on any given night, so we still see each other after that. We also make a lot of effort to spend time with the DCs (also teens), taking them to their clubs, watching sports, theatre, just going shopping and cooking together.
Really it's all about give and take, we quite often get clashes but because I do sports too it doesn't always fall to me to ferry the DCs about. It does tend to be me who minds the calendar and alerts him to clashes, but he pulls his weight with the actual going to things.
I tend to think you really do need your own hobbies, and they need to be out of the house so they don't just get shoved to one side all the time. It doesn't have to be sport, maybe exercise classes, a choir, a knitting or photography club, anything that takes your interest. I follow various local FB pages and groups, they are a great way to find out what is going on in your community that you might like to get involved in.
