A cheating partner often becomes unusually protective of their personal space and devices. They might change passwords, take calls in private, or suddenly use their phone or computer more frequently but away from you. This heightened secrecy can be a warning sign, especially if it contrasts sharply with their previous openness. If your partner starts spending more time with new friends or acquaintances and excludes you from social events, it could indicate they are building connections outside the relationship. They might also become vague about who they are spending time with or why.
