The main thing in a relationship?

All people are asking this question. I would like to express my personal opinion. Even if I am not so many years old yet, somewhere I know more, somewhere less. Perhaps those who are older than me will say a different opinion. For me, the main thing is love, mutual respect and mutual understanding. These are the 3 most important qualities that I highlight. Other qualities are not eternal, for example beauty, sooner or later over time the beauty will disappear, which was in youth and what will remain? The person himself, and if you love each other, the appearance of the person will not be important to you. Therefore, I would like to wish those who read this to find the person in whom these 3 qualities will prevail! Otherwise, you can always agree) Let people be different, but you can always sit down and discuss everything peacefully. All the best!
