. You have your self-esteem
Hurt disappointment and anger doesn’t build confidence or self-esteem. Your self-esteem is built upon being in perfect relationships. Why compromise your self-worth or self-esteem for someone who is not deserving of it? Perhaps looking inwards at those relationships that count should be a priority rather than offering it all to someone who doesn’t desire it. You should keep only a relationship that credits you rather than discredit you.
