What Happens To Your Mind During Coming Together & Parting Ways In Relationships?

Sometimes, when you are in a relationship with someone, life can throw unexpected events your way that force you to separate. Or the person you love can change somehow, and you will have to deal with it. When this happens at a young age, it can be really hard to handle. Honestly, it feels unbearable.

What is this thing called love?

The chemical process that happens in the brain when you like someone is defined as love. It is like an addiction that you cannot avoid if you keep thinking about it for a long time. It is similar to using a drug for a long time. You might think it is love, but it is actually caused by passion. If someone triggers this process, it can go on for a long time. It also changes your ordinary lifestyle. You adapt to it and might not realize it. But when you become close to someone because of love, your life after that is completely different from before. Day by day, you unconsciously flow in a new direction.


Love is a special feeling you have for someone. It starts with one or more things that make that person attractive to you. For example, it could be their,


  • Looks
  • Voice
  • Way with words
  • Behavior
  • Interests
  • Sense of security
  • Attention
  • Abilities
  • Popularity

It is these qualities in them that draw you towards them. And as you get to know them better, you start to find their other qualities unique and attractive too. It means that a certain percentage of all the other things about the person you like will gradually attract you. Those things become very special to you.

Why do you devote yourselves to someone else?

You do everything to bring yourself mental satisfaction. Sometimes, there are people who make sacrifices, even when they know they will not gain anything in return. Once you become addicted to that person, it is hard to let go, even if you see their flaws and know it does not make sense. The mind is still trying to maintain that attraction. Your mind just keeps trying to hold onto that attraction. It is like your mind and body have become dependent on the unique feelings that a person gives you. It is exactly like being addicted to drugs.

What happens in a breakup? Why does it cause us so much pain?

The process I mentioned earlier keeps happening because of the things you hear or the feelings you experience. As you think about it day by day, your mind stores all the related feelings and information. Your life also adjusts to this ongoing process.

But then, unexpectedly, a message reaches your brain that the person you love is moving away for some reason. In response, your brain sends a signal that you cannot imagine living without them. It is because your brain’s chemical process has already gotten used to the whole plan.

Once that person has gone, it is hard for your brain to stop that process and bring you back to who you were before. You simply become accustomed to a life that depends on that person. So, when they leave you, it becomes incredibly difficult to continue living within that plan.


At this point, your mind has two options to bring you back to normal.

  • Try to get back together with that person and continue the previous process
  • Break free from the addiction of depending on them and stop the previous process. (Train our mind to follow a new plan.)

But the easiest thing mind can do in this situation is to quickly get closer to that person and continue this. Unlike the second option, fully freeing yourself from it takes time and requires proper mental training. Therefore, your brain constantly wears you down, urging you to bring that person back into your life.


It pushes you towards the first option, which is easier for the mind. This is essentially what we perceive as an addiction.


In this situation,


Your mind keeps reminding you of everything about that person, like their memories, looks, way of talking, and personality. You’re more likely to remember these things than before. Your mind tries to connect everything you see and hear to them. This is the pain of a breakup.


To put it simply, this process is so terrible that you might,

  • Lose appetite
  • Eat uncontrollably
  • Have trouble sleeping
  • Wake up in the middle of the night
  • Waking up from sleep brings a sense of dullness and unpleasant feelings
  • Get angry with family for no reason
  • Lose interest in things you used to love
  • Feel lifeless and hopeless
  • Have suicidal thoughts

It can get really bad after a serious breakup, to the point where you might even lose your will to live. You might end up depressed or close to it.


During this time, what often occurs is getting trapped in a circulation of thoughts. The only way many might see to escape the pain is to try to get back together with that person or do something harmful to ourselves or others. Sometimes they might even consider taking their own lives. How this affects, each person is different.


For this reason, after a breakup, all sorts of things can happen. You might,

  • Get angry and vent to others about the sacrifices you made or how unfair it all is.
  • Feel sad and try to apologize with long texts and phone calls.
  • Start fasting intermittently
  • Try to take revenge on yourself in big or small ways.

You might be wondering where you stand right now. But no matter where you are, even if the person you loved is the best and most beautiful person in the world, you can still recover fully. This means you can change your mindset to the point where their memories do not affect you anymore.

How can you get rid of this pain?

You need to understand what’s going on in your mind and the reality of your attachment and accept that it has come to an end. You cannot follow a method without knowing any of these things. There is no point in trying to do anything without understanding everything and properly ending your relationship. Ending it means getting out of there in the right way and committing to no contact 100% properly.


From there, the foundation you need to mentally let go starts to build. By sticking to the no-contact rule, you can for sure move on mentally. The purpose of this article is to give you that basic understanding.
