He might be extremely angry at first. After all, betrayal in a marriage is a very serious matter, especially for a soldier who may have been away from home for long periods, serving his country.
He could also be very decisive and immediately take steps to end the relationship. His military training may have instilled in him a sense of discipline and quick decision - making, so he may not tolerate such behavior and choose to move on with his life as soon as possible.
Another option is to seek counseling, either individually or as a couple. Counseling can help him understand his feelings better and also give his wife a chance to explain herself more fully. Maybe there are some underlying problems in their relationship that led to this situation, and counseling could help them work through those problems.
He could first try to have an open and honest conversation with his wife. Listen to her side of the story without immediately getting angry. This can help him understand the root of the problem.
A husband could also choose to distance himself from his wife emotionally. He might start spending more time away from home, either at work or with friends. This is his way of creating a buffer between himself and the painful situation until he decides what to do next. In some cases, this could be a precursor to seeking revenge or payback, like if he starts making new friends who are more successful or attractive than his wife's lover as a way to show her what she's missing.
Some husbands would choose to cut off all communication with the wife and start the process of separation or divorce without much drama, just coldly moving on.
In many stories, a husband may choose to be more rational. He will first try to have a conversation with his wife to understand why she did it. He might ask for an explanation and see if there is any chance to save the marriage. However, if he feels that he can't trust her anymore, he will likely start the process of separation or divorce. This reaction often depends on his values, his love for his wife, and his future plans.
He might be shocked and angry. The idea of his wife being in a place that is typically associated with male - centered sexual entertainment can make him feel betrayed, even if there was no improper behavior on her part. It could lead to an immediate argument and a breakdown in trust.
He would probably be extremely angry and feel betrayed. It's a serious violation of the relationship trust.
The husband's reaction could vary. Some might immediately confront the wife and the friend, demanding an explanation. Others might be so devastated that they go into a state of denial at first. In the long run, he may choose to divorce as it's a very serious violation of the marital bond, or he could try to forgive if he truly loves his wife and believes in the possibility of rebuilding trust, but it would be an extremely difficult process.
First, he might feel angry. It's a natural reaction. He could confront his wife directly and demand an explanation. For example, he might say 'I know what's going on between you and your boss. Explain it to me now!'.
The husband might choose to have an open and honest conversation with his wife. He should express his feelings calmly and listen to her side as well. This way, they can both understand what led to the situation and decide if they want to work on the relationship or part ways amicably.
