Your boyfriend may begin to change his behavior because he feels guilty about cheating. These behaviors can be positive or negative. Typical changes include:
😀 Buying gifts for no reason.
😀 Going out of his way to be helpful and caring.
😀 Picking fights with you.
😀 Being more moody.
😀 Smelling differently (e.g. another person’s perfume or cologne)
😀 Paying extra attention to his appearance (e.g. clothing, new haircut, going to the gym)
😀 Lying about things that are both big and small.
😀 Saying different phrases that he usually would not.
😀 Keep in mind that cheating is not the only explanation for unusual behavior.
