The question "Is he cheating? Man I don't know" resonates with a common uncertainty people face in relationships. Several signs may indicate possible cheating, though none are definitive alone. Common signs include emotional distance, secrecy about whereabouts, increased defensiveness, changes in phone behavior, less intimacy, and unusual anger or criticism. Noticing behaviors like hiding a phone, avoiding sharing information, sudden defensiveness, or staying out late without explanation can be concerning. It's also important to consider if the partner seems emotionally withdrawn or overly critical. These signs warrant open and honest communication as a next step to clarify concerns rather than solely relying on suspicion.

This uncertainty is also echoed in the lyrics of Rihanna’s song "Breakin' Dishes," which expresses frustration and confusion over a partner’s behavior—being out late, not checking in, and the doubt about cheating without proof.

To summarize, if there is doubt about cheating, look for consistent behavioral changes such as secrecy, emotional distancing, defensiveness, and changes in intimacy, and try to address these through a calm, honest conversation.
