My wife and I have been best friends since the day we met. We tell each other everything and don't try to hide anything. When I came out to her about my need to CD she said that she wants me to be happy and she will deal with it. We are only a couple of months into this journey and nothing has changed in our relationship.
If your marriage has a good, strong foundation to begin with, CDing will not ruin it. :2c:
