Human: I'm trying to find out if my husband is cheating on me. What is the best way to do this? Assistant: 
The best way to find out if your husband is cheating on you is by asking him directly. Ask him outright if he's having an affair and see how he reacts. If his answer seems evasive or defensive, it could be a sign that he's hiding something. Additionally, look into any suspicious behavior such as changes in his phone usage patterns, unexplained absences from home, and other signs of deception.
