The first piece of advice for dealing with selfish people is to be real with yourself. Accept that the self-centered person might never consider your needs first. As much as this friend or lover means to you, know that they have no regard for others’ feelings or welfare. They can have moments of generosity and charm, but for the most part, they simply lack the skill or willingness to be thoughtful and considerate. This knowledge will give you a clear understanding of where you stand in the relationship.
