From Personality Junkie:
“You complete me.”
“I can’t live without you. I need to hold on to you.”
Need-based: “I need you.”
“I only want to hear positive things about me or our relationship.”
Founded on infatuation, imagined ideals, and ego needs.
“You enhance me.”
“I can live without you. I thereby grant you space and freedom.”
Want-based: “I want you.”
“I want you to be honest with me and with yourself, no matter what.”
Founded on a more honest and realistic appraisal of oneself and one’s partner.
