Does the husband's insistence on traveling, despite his wife's saying "It's either me or the camp" and her threat to leave the house, affect the marital bond? And should he have canceled the trip in this case?

The husband's travel does not affect the marital bond, nor is he obligated to abandon his travel if his wife becomes angry. Rather, he should consider the predominant benefit. If the benefit of travel outweighs the harm of the wife's anger, then there is no blame upon him. It is not the wife's right to prevent him from traveling. The fundamental principles of the marital relationship are affection, mercy, and understanding.
