When someone can't bother to meet with you or to call you, and answer the phone when you call, remove that person from your life. Why? Because everything is based upon their terms. It's never going to be about having a mutual relationship; it's going to be circumstances that benefit their terms and selfish pleasures.
It's a funny thing about life, once you begin to take note of the things you are grateful for, you begin to lose sight of the things that you lack.
