Hello Tigerifictiger and welcome to a2k. I'm wishing you well, but not sure exactly what you mean by "quality time" so I couldn't answer your poll. Do you mean sex? Do you mean going out? Do you mean being together in the same room and not screaming at each other?
I assume your husband's schedule is job-based. Are you unable to adjust your schedule to your husband's because of your own work or because of personal preference? Would it make that much difference? Is there some reason you can't hold off on dinner until he gets home? If he works until 8-9 during the week, I can't imagine what sort of cultural event would start late enough for you both except the second set of a jazz show.
Speaking as a married woman of many years... these habits change depending on jobs, children and a host of other things. It is also important for each person in the couple to have some time to themselves. It is unlikely, unless you are in some extraordinarily social milieu, that you will be going out as often as you did before you married, particularly if you were not living together. The fact is, most people enjoy staying home and being cozy... cooking together, reading, being on the internet, watching TV, and attending to all those projects that make life interesting. These can be companionably done together or side-by-side. Mr.P and I used to have what we called "dueling book" sessions. We'd get comfy in the living room and each read our own book, punctuated in a friendly way with occasional bursts of laughter or snorting wherein we'd feel compelled to share a little from our respective books. THIS was quality time, for us.
