A toxic person will deceive, manipulate, and gaslight you to avoid admitting they are wrong.
Making mistakes and hurting the ones we love is part of being human. When you accidentally cause somebody pain, the right thing to do is own up to your mistakes and apologize. However, in order to do so, you need to be able to put your pride and ego aside; this is something a selfish, toxic person cannot do. Rather than admit that they are wrong, such a person will twist reality and blame you instead.
Toxic people use various manipulation tactics to absolve themselves from blame.
Sometimes, they might genuinely be incapable of seeing that they have made a mistake. For example, someone with Narcissistic Personality Disorder (NPD) might not see that they are at fault simply because they truly believe that they are never wrong. Being around such a person is exhausting and draining. No matter how much you try to explain how they have hurt you or why what they have done is wrong, they will never listen. What is worse, they may begin to deceive and manipulate you. In other words, they turn things around, twist reality, and make you believe that you are the one at fault. When this happens often, your mental and emotional wellbeing will begin to deteriorate.
Unsurprisingly, being around such people can destroy your happiness and health.
Nobody deserves to be in a relationship or friendship with someone who cannot admit when they have made a mistake. If someone truly loves and cares for you, they will apologize for hurting you; in fact, seeing that they have hurt you would also cause them pain. Being around people who make you feel like everything is your fault can leave you feeling worthless and insecure. Do not let yourself be dragged down by toxic people. Instead, find genuine and kind-hearted people who value you enough to admit when they haave wronged you.
It is important to know that waiting for a toxic person to change is one of the most self-destructive things you could do. Instead of wasting your time fighting for someone who cannot treat you the way you deserve to be treated, let go. You deserve more.
