What do you think about open relationship during marriage.

My wife and I decided to become consensually non monogamous and begin to have other relationships with otherpartners but telling each other each time when we see another partner. In my opinion this helps us a lot in communication. When we were a simply monogamous couple, and I found a girl was attractive I could not tell my wife, but now I tell her everything. I feel like I have even more connection with her now. We strictly separate love which take years to be built and attraction.

I would like to have your opinion as a progressive Christian what do you think about open relationships.
