If you can avoid interacting with them at all, it may be best for everyone. If you have to interact with this individual, keeping things as calm and civil as possible could be the most beneficial course of action. Some people who feel hatred toward others might try to pick fights with them.
Avoid your hater when you can, but if you must engage, try to stay calm and collected.
Reflect on your interactions with them to try to understand why they hate you and patch things up if you can, but realize there may not be any valid reason for them to dislike you.
There's a quote by an unknown author: “A person hates you for one of three reasons: 1) They want to be you 2) They hate themselves 3) They see you as a threat.”
The psychology behind the silent treatment is that it can be a mind game for some people and, in some cases, can be used as a form of manipulation. Along with the emotional roller-coaster, it tears down your sense of self-esteem and sense of self-worth.
Most psychologists indicate that it depends on the situation. When silence, or, rather, the refusal to engage in a conversation, is used as a control tactic to exert power in a relationship, then it becomes "the silent treatment," which is toxic, unhealthy, and abusive.
Don't try to justify your actions. For example, if your crush hates you because you made fun of them in public, you could say, “Hey, I've had some time to think about that, and I wanted to let you know how sorry I am. That was not right and I won't do it again".
Hate usually stems from fear, insecurity, or mistrust. Do not compare yourself with others. Strive to be the best version of yourself instead. When you feel hate or anger, it is best to take a step back and avoid reacting in heat of the moment.
Misanthropy is the general hatred, dislike, distrust, or contempt of the human species, human behavior, or human nature. A misanthrope or misanthropist is someone who holds such views or feelings.
If someone displays unmanageable emotions and easily flies off the handle, this is a serious red flag. Responding with uncontrollable rage or the "silent treatment" could point to abusive (physical or emotional) behavior in the future, says Trombetti.
Over time, the use of the silent treatment can become emotionally abusive. Research has found that people who received the silent treatment experienced a threat to their needs of belonging, self-esteem, control, and meaningful existence.
What happens emotionally when someone ignores you?
Being ignored creates feelings of self-doubt, feeling a lack of control, and feeling not worthy of attention. Knowing appropriate responses to people with whom you differ is helpful in managing tense relationships.
The silent treatment, or stonewalling, is a passive-aggressive form of manipulation and can be considered emotional abuse. It is a way to control another person by withholding communication, refusing to talk, or ignoring the person.
Respond kindly or don't respond at all. Either way, don't give them hate back. If you feel the need to respond to better understand why they feel that way, or think an appropriate comment could heal the situation, then go for it.
Usually, the haters simply criticize and move on. And that means that you can safely ignore them and continue doing your thing. But that is easier said than done because we all like to be validated. Some people like it more than others, but everyone wants to be respected and appreciated to some degree.
