Why does breaking up hurt so much?

It can be extremely painful transitioning out of a relationship regardless of the terms you end it on. It's normal to feel upset when you are attached to that person emotionally.

Because you put a lot of effort into a relationship, commit yourself to that person and do everything for them that it's natural to attach yourself to them emotionally. All the memories will come flooding back and you'll wish it never ended but depending on the circumstances, you might just be better off single for a little while at least. It may hurt even more depending on how the relationship ended but if it's not meant to be, it's for a reason. If not that person, there will be your soul mate out there somewhere.

Because of the ties or bonds you made from each other.. in other words the memories both good and bad

Because you give yourself to another person (emotionally, spiritually and sometimes physically) and expect that the person will do the same for you. When they do not give 100%, it is very hurtful to learn that.

Being in a relationship means you always have someone there. Someone who understands, someone supportive, someone who loves you. Especially when you're younger, being loved and understood is very important. For a lot of people, SO's are more important and closer than friends.After a break- up, that feeling of being loved, being understood and being cared for is suddenly taking care of you. Sure, you have friends, but a relationship is so much more intimate. This feeling of loneliness and ''I'm never going to find anybody'' goes away, but right there and then, it feels like you're all alone in the world for the first time.

Because it is the severing of a friendship that clearly had meaning in your life. It means the end of something that used to be.

because your losing someone you were attached too, and now you have to be without him/her, you shared yourself with them and now they are gone.

It is because you are separated from someone you trusted, loved, and gave your heart to. Speaking from personal experience, after losing my girlfriend, I never felt sadder in my life. Every day was bleak, and honestly, I didn't have the power to right myself. However, in the end, I realised that it wasn't over. There are more people out there than I realised. I forced myself to forget her, even though it was hard... then the pain eventually subsided. that is how I got over it..

It hurts because you get used to a particular person and his/her absence leaves a void that seems unbearable. Sometimes it is because the ego gets hurt more than the loss of a relationship.

Losing someone you love hurts psychologically and physically. We are used to having this person in our brain and a break up forces us to erase the person in an instant manner in our head.
