Relationships are hard. From the beginning of your marriage to the point at which you decided to end it, you likely felt every hardship along the way. Many people feel this way, and while you likely hoped that your relationship was different, marriages that once seemed so perfect could easily show cracks and damage after a time.
No one knows your children better than you do. This is why you likely feel most capable of making decisions in their best interests as you navigate the divorce process. Even if you may not have seen the divorce coming, you're a realist, and you may have explained to your kids that although their lives are about to change, that does not mean their lives will be ruined. From speaking to friends who have gone through similar experiences, you've learned that all children adapt to post-divorce lifestyles in their own, unique ways.
