And of course, let each other know when we'll be seeing someone else.
Rule 4: We don't date friends or anyone that we know—including anyone we are friends with on social media.
We were both always aware of the existence of other lovers, but it was clear that we were each other's favorite.
It occurred to us that we could keep the excitement and variety, and still let ourselves fall in love with each other. And since then I’ve gotten a lot of questions about how we make it work and why we would even do that in the first place.
We don’t get mad at each other if something happens that feels uncomfortable as long as it’s not a violation of an existing rule; we learn from it, and make a new rule.
