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

Right now we don't have much time anymore for our friends, but I let my husband play in the basketball league since it's his passion and stress reliever :) I have observed that husbands need more boys night out time than the wives because it keeps them sane. hehe. But all you have to do is to trust your partner. What I do is I usually just have coffee with my friends so that I can go home early for my baby :)
