You may find that quiet time and vegging can be done together. Going out (even grocery shopping) wears me out and I need a lot of time at home to just chill. But it's fine if my husband is here, my "quiet" time is just being at home. We are lucky that we share a lot of the same interests so we can usually find something on TV that we can agree on. We have our Monday night, Thursday night, Friday night and Sunday night shows, so we always try to plan to watch those together. We don't have a big house (downstairs is just 1 big room LR/kitchen, upstairs 2 bedrooms) but I can always go take a bath or go upstairs and go be alone if I want to. Sometimes I will go out on the patio and read and if I turn off the TV to read he is really good about using his headphones, especially at night.
You'll figure it out. I'm sure he wouldn't mind you "kicking him out' if he gets to go hang out with his buddies or something. It would be better than you sitting back and silently hoping he leaves! It doesn't have to be mean - just tell him you are busy/tired/need to relax and he's on his own for dinner one night. Then eat ice cream for dinner and watch a movie! (I can't be the only one who sometimes just wants ice cream for dinner, right?
)
Seriously though, you may just fall into a new routine you'll like just as much.
