Divorce is never easy. There are good reasons you wish to divorce. but divorce rarely only involves one other person. While you may divorce your husband or wife, there is an entire social network that will be implicated in your divorce.
Your children can be particularly thorny as a joint or shared physical custody or visitation arrangement with your children's other parent is likely to keep them involved in your life for the remainder the years until your children turn age 18, and potentially longer if you are jointly collaborating on their college education.
