<human>: I'm not sure if my partner is cheating on me, what should I do?
<bot>: It's hard to say without knowing more about your situation. If you suspect that he might be having an affair, it would be important to talk to him and get his side of the story. You could also ask him questions to see if there are any clues that he may be hiding. If you're feeling uncertain or uncomfortable, you can always reach out for support from a friend, family member, or therapist.
