Infidelity in a relationship is not always obvious. Some affairs aren’t discovered until someone is caught or confesses. So you may not always be able to know if your partner is cheating on you. “Depending on the personality of the unfaithful person, infidelity can be very apparent or very well-hidden,” explains Dr. Carla Marie Manly, clinical psychologist and relationship expert who has worked extensively with clients on their infidelity issues.  However, there are some signs that could indicate infidelity — or at least, the potential for it. “Most partners who have been betrayed say their spidey senses tell them something is up with their partner, even when the other person denies it or fails to respond to attempts to connect or find out if everything is ok,” says Dr. Dana McNeil, licensed relationship, marriage and family therapist and founder of The Relationship Place in San Diego.  For example, she continues, your partner might be “emotionally disconnected, changing or creating new habits of dress, spending more time away from home, or be on their cell phone more.” You might also notice that your partner has a dwindling interest in your daily activities or in sexual intimacy with you.  “Other more subtle and harder to pinpoint signs are when a partner is being unresponsive to their partner’s emotional needs, is not open to hearing the other person’s feelings without getting defensive, or exhibits indifference to make amends when conflicts happen,” Dr. McNeill says. Sometimes, the cheating partner might also be more easily annoyed, angry or short on patience.
