Emotions are contagious. This is why you need to understand the act of blocking toxic people from your life. It doesn't matter if it is online or in real life. The things you read and watch affect your brain in ways you could never imagine.
I can't emphasise enough how important it is for you to walk away from toxic partners.
People in this part of the world only recognise physical abuse. But psychology abuse and emotional abuse and verbal abuse are even more destructive.
When you come out of an abusive relationship, it would be nice to do a brain scan and see how much damage has been done to your brain by abuse.
Abuse causes you more damage than you could imagine. Some of us who love ourselves so much are in the habit of running from toxic people. It is not cowardice. It is self preservation.
An abuser projects the wrong emotions to you and you become his/her dumping ground for negatively inclined emotions.
For instance, when you watch a movie, you may not know that the movie you are watching commandeers your emotions. Your brain responds to each scene accordingly. This is why you should shield your children from horror movies, especially in their younger years. Horror movies can cause brain damage in a child. In fact, a child can go into shock as a result of a movie scene.
Protect yourself and your loved ones. No one else would do it for you.
