Send a sexually explicit short message to meet her husband and another woman. Is it because he cheated? No matter how much I torture him, I won't admit it. What should I do?

Don't make trouble, secretly investigate and collect evidence of his cheating. If there is evidence, you have the right to speak and the legal initiative. Arguments without real evidence are not good for you, and the relationship between husband and wife is not good, which will make your life worse. So only when you have a good grasp of the real situation can you talk to him. It depends on the specific situation, whether to persuade three people to live apart to save their marriage or to sue the court for divorce with evidence. Marriage doesn't know how to ask me.
