Shriver Divorced Arnold Because He Lied.
Even if one partner has been unfaithful to the other, a relationship can still be strong. In Maria and Arnold’s case, however, this is not the case. In the wake of Shriver’s discovery of her husband’s infidelity, she was pushed to the breaking point. In addition, she was unable to stay with him because of the actions he had taken in the past.
The most difficult part was adjusting to Arnold’s silence for the past 15 years. In spite of the fact that she had forgiven him, Maria was certain that she would never look at him the same way ever again. Even after such a betrayal, they could only hope to maintain their friendship.
