He should try to stay calm and talk to his wife rationally.
The husband has a few options. Firstly, he can try to keep his cool and ask his wife and the lover to explain themselves. He needs to listen carefully to their reasons, although it will be very difficult. Another way is to step back and give himself some time to think. He can go to a friend's place for a while and come back when he has a clearer head. If he decides to save the marriage, he should suggest marriage counseling. If not, he has to think about how to separate things amicably, especially if there are children or shared property involved.
He might be extremely angry and immediately ask his wife for an explanation.
The husband should respect his wife's privacy and immediately stop reading or watching. He should then have an open and honest conversation with his wife about how he came across it and assure her that he respects her privacy.
She could confront both of them. Let them know that she is aware of what's going on and that their actions are unacceptable. This way, she takes control of the situation and doesn't let them keep her in the dark.
He should be understanding. It's a normal part of human sexuality. He can communicate openly with her about it if he feels comfortable, but also respect her privacy.
He should first stay calm. Reacting impulsively will only make things worse. Then, he can talk to his wife privately when she's sober and express how he feels about what she shared. For example, if she shared something about their sex life, he can gently tell her that it made him uncomfortable.
Well, initially, he should avoid jumping to conclusions without proper evidence. Once he's sure, he needs to think about his boundaries. If he wants to repair the relationship, communication is key. He can express his hurt and disappointment, but also listen to her side of the story. He might need to seek support from friends or family during this difficult time. And if he decides to end the relationship, he should make sure to handle the legal and financial aspects properly. It's a very tough situation, and there's no one - size - fits - all answer.
He can start by having an open conversation with her. Just tell her how he feels about it. For example, if he's worried, he can say that. He could also suggest some alternative activities that they can do together, like going to a movie or having a dinner date instead of her always going to the bar.
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!'.
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.
