Hi N.,
My husband and I were having this conversation just 2 nites ago. We both work full-time and have 3 kids now (it's a whole new ball game when they outnumber you :)ages 4, 3 and 18 mos. -- so, here's our take on this topic:
(1) prioritize chores -- e.g. clothes are clean, but not always folded, sometimes folded, but not always put away ...we often plan for a nite of folding loads of laundry and use that time to chat or watch a movie while we fold. dishes don't have to be washed EVERY single nite and once washed, they'll get put away eventually.
(2) Multi-task w/ creativity-- e.g. I've learned to clean the main bath while my girls are in the tub, so while they're splashing away in a bubble bath, I'm cleaning the bathroom -- 2 birds w/ 1 stone ;)
(3) plan for date nights at home -- my husband and I are "Lost" junkies, so every Thurs. we knew that the kids need to be asleep by a certain time, we'd plan for our date night snack, head to the basement and snuggle up with popcorn and our weekly dose of "Lost" , we also have our favorite old sitcoms on dvd, so some nights we have a "Frasier night", e.g.
(4) b/c we are often pooped and sometimes fall asleep before we can spend alone/intimacy time, we've found crashing for a few hours (10 pm to 1 am, e.g.) and then spending "time" together and going back to sleep works too...
We also pay our daycare provider to keep them overnite from time to time, you might want to look into a sitter service or ask co-workers, church members, etc. for referrals and give yourselves an overnite date night.
You will find a way make it work, it takes effort and planning though, otherwise it doesn't happen!
