Ghosting is an avoidance behavior that reflects some self-limiting belief by the ghoster. Always. A person who is self confident and secure, maybe even with a dash of emotional intelligence, will tell you that the relationship does not feel like the right fit for long term. Now if they do that, accept it as a gift and don’t try to convince them otherwise. It does not mean that there is something wrong with you. Long term is a big deal, and having the insight and courage to recognize that a particular situation does not seem like a long term fit is invaluable.
