The article consists of two parts, the first describes the intentional or unintentional methods of messing with the other person and emotionally disrupting them, the other part states the possible reasons behind it.
So how to drive someone nuts?
1. Repeatedly point out self-contradictory behavior, accuse of hypocrisy.
2. Act flirtatious, encourage someone to commit an act of marital infidelity.
3. Make someone walk on eggshells. Switch back and forth between acceptance and rejection.
4. Confuse them, give mixed signals.
Reasons:
1. Get rid of the person, especially a competitor. Push someone away so that they no longer bother you. Here, driving someone insane is an equivalent of a psychological murder.
2. Expose them, especially when someone tries to put on a mask of sanity. By triggering the onset of insanity you show them for who they are.
3. Escape from your own craziness. By driving someone crazy you will feel more sane by comparison.
4. Much less sinister: Find a companion or a soulmate to share your craziness with.
This is in a nutshell. Could there be any other forms of emotional manipulation? Did you encounter them in your daily life? Do you think people deliberately tried to push you over the edge? Or were you the one doing it? If so, then why?
Personally, I wonder how much of it is indeed intentional. I mean that intentional manipulation requires a high degree of empathy (not in a positive sense, mind) and few are capable of it. The majority of people act on impulse. And in toxic relationships, which are crazy by default, most rarely think outside their straight jacket.
