You would be surprised to see the level of immaturity during a divorce. The advice I give all of my clients is this “even know you are not in love with the other person and act as if you are new to each other (and in parts you are) for your sake, your ex’s sake, and the kids sake. It will only do you good if you do”. If you follow this advise I promise you will have a better outcome than 90% of the divorced society.
