Like many PPs I agree that it's so important to have an individual life even while married. My DH and I both go out seperately to hear music, catch up with a friend, go to a lecture, a movie, on and on. We always come back energized with stories for each other and actually I feel like it builds up our love for each other, since we know we can continue to grow as people and engage with the world, and still have the security of a marriage and spouse.
We both try to look nice and put together, but not for flirting with strangers.
