She should immediately ask them to stop and leave the situation. Then, she needs to have a serious conversation with her husband about boundaries and respect in their relationship.
He should try to be calm. First of all, he should give her some privacy immediately to let her compose herself. Then, when they are both ready to talk, he should approach the conversation with an open and non - judgmental attitude. He can say something like 'I understand this is a normal part of human sexuality, but I was a bit surprised. Can we talk about how we feel about our sexual relationship?'
He should respect her privacy first. Everyone has sexual needs, and it's normal. He could have an open and honest conversation with her about their sexual relationship and any unmet needs they might have.
One reason could be that the husband has a higher sex drive than the frequency of their sexual activities as a couple. So he resorts to masturbation to fulfill his needs. Another reason might be that he just needs some solo time for relaxation without any pressure, which is different from sexual activities with his wife.
The husband needs to be completely transparent. He should be willing to share all details about his relationship with his friend and his own sexual identity. This honesty can be the first step in rebuilding trust.
If she feels that she can't accept the situation, she has the right to think about separating from her husband. However, it's important to consider all aspects, such as financial implications, children (if any), and her own emotional well - being. It's a tough decision that requires careful thought.
This is a very inappropriate and unethical situation. In such a case, the husband has every right to be extremely angry and might consider ending the relationship as trust has been severely violated.
Well, the wife should give herself time to process her emotions. She can express how she feels to her partner without being accusatory. The partner should be understanding and willing to make changes if necessary. For example, they could set boundaries regarding privacy and respect in the home. It's about rebuilding trust and ensuring both parties feel comfortable in their living space.
The husband has to be truly sorry and show it through his actions. He should cut off any inappropriate behavior and focus on rebuilding trust with his wife.
