Why Do You Need to Compromise in a Relationship?
Let me first make a few things clear. A relationship is not only something that exists between people who get sexually attracted towards each other. In fact, you may have a relationship with everyone around you, and the relationship between you and your parents, you and your siblings, you and your friends, and the people of your society is also counted as a form of relationship.
Now, every relationship has some demands and it’s up to the two or more people to fulfill the wishes and demands of the other people in the relationship. If you remember, your parents started fulfilling your demands even before you were born. They compromised a lot for you and this is the major foundation stone in a relationship.

Any relationship in the world needs love and care and this is what is visible to others. However, what is not visible to people are the compromises and sacrifices that people make in a relationship and if you do not compromise in a relationship, the relationship would not work that well.
There is a very small example. If you have a dog whom you take out for a walk every single day, the dog has this natural habit of pooping at corners and educated people pick that up and discard it at designated places.
What if your dog gets ill and starts pooping in your home? Would you throw your pet out of your house? No, if there is no caretaker in your house, you would have to clean it yourself and this is the compromise you make in the relationship between you and your dog.
And these compromises are what make your relationships healthier with your pet. So in any sort of relationship, whether your life partner, your friends, or your siblings, compromises and sacrifices are a must.

What would happen if you are alone at home with your sibling and your sibling starts feeling unwell in the middle of the night? Would you stay rested on your bed and let your sibling deal with his/her health issues? No, you would get up, ask for the health conditions, help your sibling with the medications and if required, visit a doctor as well. And for this, you would have to sacrifice your sleep, maybe for the entire night.
Nowadays, married couples fight and split over petty things, just because they do not wish to compromise. Well, you need to understand that nothing in the world works without compromises and sacrifices and the sooner you understand this, the happier you are.
