I THINK, IF you are "all in", you can feel the value in the Other Person. Maybe there is a reason they cant respond right at this moment in time. Remember, dont switch... Trust, even when trust has been broken. Live, love. gently, with no spite.
Never apologize for having standards and expectations of how to be treated. Not at the stake of your integrity, morals, or anything else. If people can't step up, then they can step down. It's a privilege to be a part of someone's life, not a given right.
