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

Certainly not as many as when I was single. It's been 4 years to my marriage. But even now, a group of friends and I do meet up once every 2 months to let our hair down. It could be at one our place (provided the husband and kids are away) or at a faraway resort. It helps me unwind and also gives me some much necessary me-time.
