Why does breaking up hurt so much?

I think breaking up hurts because you went through a lot with that person and because of the memories you had with them you miss having these memories again and everybody goes through this. and this is just what I know :)

Breaking up hurts because you invest time and energy and love into another person. When a relationship ends, you feel pain. As time goes on the pain begins to heal.

The reasons can be different from one relationship to another, but mainly because you've invested your time, and your feelings into this person, and it is hurtful to see it come to an end. It can help to remember that you won"t be the same person afterwards, you'll be stronger, and wiser, and also, think that this person wasn"t meant to last in your life for longer, and it must be for a reason.

Breaking up hurts so much because you see yourself having a life with your partner, you spend time with them

You are losing a person who you had a strong connection with. You are losing a person in your life, who played a big role. It is much like grieving a death.

you are losing someone who has been an important part in your personal life and someone who may understand you a lot

Break ups hurt because you had an emotional bond with that person, and when it was broken you feel like a part of you was severed. But you eventually get over it.

When you are in a relationship with someone and have acquired feelings for them then it can be difficult to let go of that person. Losing someone you care for is honestly one of the hardest things you can encounter in life. Breaking up happens and it is challenging to deal with. Life is never easy and its challenges can be even harder to take on. After the break up, try to value the good times you had with that person and learn from the experience.

because you are leaving someone that you love and you know that he/she doesn't have feeling for you anymore so you feel worthless and never good enough for anyone and you start analyzing things and wondering why this person that you loved so much and gave him so much doesn't loves you anymore

I don't know but i do know that they happen for a reason, everything happens for a reason. Your breakup is just a small piece in the puzzle of your life and without it you wouldn't be able to see the whole pretty picture when your finished.
