Hurting people is natural, but lets be honest, no one likes doing it. If you do enjoy hurting people you should probably figure out why and see a therapist. Breaking someones heart is rough, out of all of the horrible things you can do to a person, breaking their heart is the worst. Sometimes we have to do it, for many different reasons. Everyone hurts everyone, it just happens.
There are many reasons that people hurt other people, whether that be in the dating world or just during friendships. Sometimes we have to hurt people in the moment rather than prolonging it and waiting for months to tell them something horrible, such as the fact that you might not like them as much as you thought. That happens a lot, we get caught up in our feelings and think we are into someone more than we actually are and then don't realize it till we're in too deep. When we go into the world of dating, typically we expect to get hurt, but we never want to be that person that hurts someone else.
Hurting someone is sometimes the way to happiness. That sounds sadistic, but hear me out. If you are friends with someone or dating someone toxic,it isn't a bad thing to cut them out of your life. Maybe they are into drugs, or are emotionally draining and you can't take that anymore, it is okay to hurt those people and cut them off if they are making life a little more difficult on you. Maybe your family drags you down and your tired of it. Whatever the case may be, you might have to hurt those people in order to grow as a person.
At the end of the day, it is about your own happiness and how you view yourself. Although it is really hard, and you might feel guilty, it is okay to hurt others in order to keep yourself happy and have a positive life. No one owes you anything, and you don't owe anyone anything. I think we often times forget that. We often times feel obligated to keep others happy and that really shouldn't be our job. Happiness is something that has to be found within yourself.
I will be the first to admit that I am bad at hurting people, and also very bad at cutting people off. I feel like everyone deserves a second chance, but I usually give people more than that. Recently, I have started taking responsibility for my own happiness and things are changing, people are also getting upset by the fact that I am finally doing this. Because of their negative attitudes, I decided to cut them out of my life because that is what I needed to do. Don't be scared to hurt people, because chances are in the end you are going to feel relived.
