This really depends from person to person since breadcrumbing can be either intentional or unintentional. When it's intentional, it's not due to a lack of manners and they know exactly what they're doing. Occasionally, accidental breadcrumbing happens when someone isn’t sure how to communicate their feelings about a relationship. For instance, if a person is confused about their feelings for you. or feels afraid of rejection and doubts how you'll respond to them, that's when poor communication enters the situation. However, despite the intent, breadcrumbing hurts and delays people from resuming their quest to love. If someone does this with you, it’s not any less bad than when it’s purposeful.
