How often do you and husband have a "girls night out" and a "boys night out" without each other?

Not as much as before haha. We like to joke that we are quite interdependent on one another but I suspect our separate social lives have dwindled because we are far too exhausted to go out (our friends are the same haha). For an actual boys/girls "all-out night out" -- I'd say he goes out with his friends once every three months and I do so when I am back in Singapore, which is 1-2 times a year. It depends a lot on our friends really; most of us are married or in committed relationships and we've outgrown the crazy nights. When we do go out without each other, it's mostly coffee and simple dinners with friends, which occur maybe once every two weeks.
