This is highly unethical. A marriage is based on loyalty and trust. What your wife's best friend has done, if it actually happened, is a serious breach of moral and relationship norms. It can lead to the breakdown of your marriage, cause emotional distress to your wife, and damage multiple relationships all at once.
This is an extremely unethical situation. Firstly, it violates the trust and loyalty in a marriage. Your boss's wife has broken her commitment to her husband. And for you, it can cause a huge mess in your workplace relationships. You should probably distance yourself as much as possible to avoid the potential fallout.
You should probably keep it to yourself for starters. Telling anyone could cause a lot of drama. Then, try to avoid any further inappropriate contact with her.
No, this is not normal in a typical friendship. Such behavior involves sexual activity which is inappropriate between friends. Friendships are based on platonic relationships, mutual respect, and shared interests.
Well, without more details, it's hard to tell the exact story. However, perhaps she has a hobby that she's really passionate about. And your best friend might be involved in it too, like if she loves gardening, he might help her plant new flowers every spring. Their story could also involve how they met, whether it was through mutual friends or in a more unexpected situation like at a concert.
Sharing such a story is highly inappropriate. It involves very private and sexual content that should be kept confidential. Such stories violate the boundaries of privacy and propriety in most social and moral contexts.
There are so many possibilities for this story. It could be a heartwarming tale about how she helped someone in need, or it could be a story related to a hobby she has that has had an impact on your best friend's life. Without more information, it's hard to say exactly what the story is.
This kind of situation goes against basic moral and ethical principles in relationships, and we should focus on positive and healthy relationship topics instead.
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.
No, it's not ethical at all. In any society, there are moral boundaries, and having a sexual relationship with your best friend's wife and impregnating her goes against all principles of loyalty, respect, and friendship. It can lead to a whole host of problems like family breakdowns and emotional traumas for many people involved.
