<human>: How do I know if my boyfriend is having an affair with his secretary?
<bot>: If you suspect your boyfriend is having an affair, the first step is to confront him. Ask him directly about any romantic or sexual relationship he may be having outside of your relationship. Listen for any signs that suggest he is being dishonest and keep track of his behavior over time. Additionally, consider talking to friends or family members who may have noticed changes in your partner's behavior or attitude. Finally, it can help to look into the possibility of an affair by searching online or using a private investigator.
