I've always been a proponent of keeping things mysterious and not spending too much time with a significant other. In fact, I like to hear about my boyfriend going out and being hit on by other women (or other men—I'd say that gives him an even shinier seal of approval). Then again, I've never been married. I don't have children or a home with anyone else. I also think I'd react very differently to the hall pass idea if my partner proposed it first.
Would you try out a hall pass to strengthen your relationship? Would it work?
