You don't have to stay open to and respond timely and meaningfully to people who have been flaky and inconsistent in their communication with you. You owe them nothing. Save your emotional resources for the people in your life who are consistently available for you, make time for you, and consider your feelings and perspectives. If you have a good heart, you need to protect it, as there are many people in the world who take advantage of others for their own personal gain. Love yourself first, and don't tolerate or enable the poor behaviour of selfish people. A person who really cares about you won't waste your time and drain your energy as it suits them when they're in no place to offer you love and companionship. They would set you free so you could be open for a connection with someone who really cares about you and has time, energy and emotional space for you. A person who is inconsistent and trails you along is self-absorbed and not capable or appreciating your beautiful soul. Do not give what is holy to the undeserving. Do not wait for others to respect and honour you. Respect and honour yourself and set clear boundaries.
