There is nothing more frustrating, than when a person comes in & out of your life, for instance, they talk to you, but only when it suits them. You message them, hear nothing back, until it's convenient for them. Only want to see you or make time for you, when it's good for them, & god forbid you ignore them in the same way, because this is only a one way street.
You may think you have the power over someone else when you ignore them, & truth is, once upon a time, those that used silence to hurt me, had exactly that. Power over me. Silent treatment is a form of emotional abuse, commonly used by narcissists as a way to control someone, to play games with someone's head, & make them suffer for their own twisted amusement. It makes you think you have done something wrong, makes you question yourself, doubt yourself, & if you allow it to, it can send you crazy. I know that not every person that doesn't reply to messages, is giving me silent treatment, & same goes when I don't reply, sometimes people are genuinely busy, & forget, but eventually people make time for those they care about, or class as friends, but when this becomes a pattern from a person - like game of cat & mouse, it gets tiresome, & eventually, you remove yourself from the game.
