The blatant self-interest of early infancy is tempered by concern for others and the need to repair any damage he may have inflicted. As a child his father may have been a poor or rejected consort to his mum, who greatly favoured her darling boy. A married man wants to do right by his lover, who now wishes to set up home with him and end her own marriage, which she regards as dead, though her husband wants her to stay. For more robust couples who fought, properly lost, and came to terms with the Oedipal struggle, voluntary fidelity born of love of the other is the only faithfulness worth having. Any unrealistic feelings of inadequacy or fear of failing so not wanting to compete, are to do with the Oedipal triangle. Everyone has to go through the triangular phase. Unresolved conflicts at the triangular stage of normal development are responsible for plenty of troubles later on.
