Your wife is clearly cheating on you and you can definitely confront her. This is a case of adultery. Adultery is voluntary sexual intercourse between a married person and a person who is not their spouse. But unfortunately, you can’t take any legal action against her as adultery is not a criminal offense in India anymore. Adultery was a criminal offense under the Indian Penal Code until it was quashed by the Supreme Court of India on 27 September 2018 as unconstitutional. You can definitely oppose her and your boss. You have to voice up against them because they what they are doing is wrong and it’s affecting you.
