Couples often decide to get divorced when they have issues in the marriage that they simply cannot resolve. Religious differences may prove to be insurmountable, especially once there are children. The couples may attempt to work things out at the beginning but, when neither person will compromise or change their position, they realize that they have irreconcilable differences. Divorce is the only way that they can move forward with their lives.
Why can couples not find a way to work through these issues? The problem lies in the fact that most religions require that the person believes that their way is right and that any other faith is wrong. Strong practitioners of these faiths will have a hard time suggesting that they could both be right or even that they may be wrong. They will not want to give any ground. They will only want to convince the other person to change their point of view. When both people feel this way, there is no middle ground on which they can settle.
In some cases, couples can ignore religious differences when they are dating and when they first get married. They accept that they both believe different things and it does not pose a problem. When they have children, however, the trouble begins. Both people want to raise the children within their faith. They see the other person as a deterrent to that. While they can accept that their spouse believes something else, it is harder to accept that their children may be brought up in a different religion — or choose to follow no religion at all.
This is not to say that people with different backgrounds cannot marry, but just to show why religion is one thing that may drive them apart. When it does, they need to know what legal steps to take to end the marriage.
