Doesn’t take no for an answer. No means no. If you tell someone “No” and they are still persistent in what they want from you, then this person is dangerous. They will persuade you into doing something that you don’t really want to or until they get what they want.
Controlling. Control is a very dangerous sign because control can lead to abuse. Someone who feels the need to be in control will always want the upper hand, leaving you with little to no voice. Do not trust the controlling person, because you will only be their puppet. They care more about being in control, rather than what listening to the concerns of the other person or doing what is right.
Inconsistent. If someone’s words are not fluid with their actions, just let them go. By staying, you are only setting yourself up for failure because that someone will never actually mean what they say.
