From my many years experience working with individuals and couples, divorce happens when one spouse chooses to grow, as an individual, and the other is so afraid of the change their partner goes through, so much so that they inflict force and guilt upon them ("don't leave me", "how can you do this to us", I have no life without you "). This of course achieve the opposite result. The partner get verifications for their earlier need for growth and freedom and they are more determined to divorce. It's a very difficult situation. 😐 I occasionally write about it here, on my blog.
