<human>: How do I know if my boyfriend is having an affair with his secretary?
<bot>: It’s hard to say for sure without more information, but there are some signs that might indicate he’s cheating. For example, if you notice a change in behavior or mood, such as becoming more secretive, spending more time away from home, or being unusually affectionate towards her. You may also want to look out for any unusual gifts or trips, and pay attention to the way they interact together.
