Lo and I are taking one day a week and not talking or emailing to make sure we stay autonomous and separate human beings. Now this may sound a bit weird, but even though I hate it I think it's pretty healthy. I like the image of two trees standing straight and tall next to each other blocking the wind for each other, more than I like the image of entirely mixing liquids.
From my reading it sounds like women's relationships (friendships and dating) tend to be more whole life bonded than than male female relationships. My intercultural counseling book that talked about therapy with lesbian couples said that this is NOT pathological or bad. But relationships do need each person to have a clear grasp of their own minds and hearts. Sometimes making intentional "alone" time and space for that is healthy. I have even heard about men and women couples who do this. My friend Nic and her husband spend Sundays on their own each doing their own personal Sabbath reflective time. Every couple is different. This may mean multiple days or it may mean one hour. Frankly right now all I can handle is one day!
Practically for me on our no talking day, I am more likely get more work done (shocker!), to meditate or pray, to focus on other areas of my life that have fallen through the cracks, like that 2 page paper I just entirely missed last week. It's a grand experiment.
