Divorce is painful, and people who are hurting often act in ways that hurt other people. They may play "divorce games" in which they attempt to use or manipulate someone in order to gain control over their lives, but the games aren't fun and they're not good for anyone involved. The games are usually not intentional, they sort of just happen unless one recognizes them and avoids them.
In the beginning of the divorce, people may actually "win" at one or two of the games. They then feel that they got something out of the mess and have some kind of control over the situation. However, divorce games result in the players feeling guilty, untrustworthy and depressed, and children are hurt. No one wins in divorce games.
