Josh and I call every other night and have since the beginning. It works best for us despite the fact we are a long distance couple. It gives each of us time to do other things because no one should ever be defined by their R alone. Gives us more to talk about too. Of course - sometimes we call each other for other reasons or because we have something we really want to share but we try not to take up a lot of time with text, email etc. We use them when necessary.
I like that we are together every weekend but still have time to ourselves during the week. It works for us.
