What are the basic needs of a relationship?

In my opinion, any relationship requires 3 basic things which are:

1. Self-respect

2. Acceptance 

3. Understanding

Life is all about inter-personal relationships. You either hurt or get hurt by anyone. Its pretty normal. There's nothing to stress about. However, things are easy said than done, but I do believe that these are the core values of every relationship and you know it with experience.

(a) Self-respect- Well! earlier I used to believe that love is more important than respect which means that you should consider love before respect. However, this is absolutely wrong as every individual has specific tolerance. Nobody would bear your rude behavior for long and I believe that is quite logical. Things get bitter when ego jumps in and you behave as a narcissists. If you respect yourself enough, you would realize that other person just has a different opinion from you and he/she also deserves your respect. A dignified individual will always consider your point of view after his/her emotions settle down.

(b) Acceptance- I believe that acceptance is highest form of love. When you accept an individual, you will give him/her unconditional love. You truly understand a person to his core and you would hardly demand any change in that person. But the fact is that you must accept yourself first and only then you would be able to accept other person without judgement. Acceptance doesn't require any further validation if you wholly accept any individual. And it requires more time than you think as you can never read a book in a day. We tend to accept so many people throughout our life but later on when we come to know about certain facts, we feel we do not know the person to this extent. Nevertheless, every individual demands acceptance from people he's close to.  

(c) Understanding- In my opinion, you can develop understanding with any person you spent plenty of time with. But remember, to be understood, you need to understand another first. 

You know how your boss/teacher/father or mother or friend would behave in a certain situation. Understanding doesn't mean that that other person will always agree with your opinion. It means that at times when there is conflict of interests between you and your closed one, then both of you have that mutual understanding that makes you respect other's point of view. However, in any relationship you must know that other person also wants you to understand him/her if you expect it from that person. It requires a lot of patience and no communication gap to develop understanding with anyone. Lack of communication would ultimately lead to accumulation of judgements, misunderstandings and wrong assumptions. Say whatever you feel like. Talk about everything that you believe is worth sharing. No matter it is about past, present or future. Bear in mind that every human has different set of values, beliefs and perception about certain aspects of life. And you must accept and respect this. It is absolutely ridiculous if you feel offended or frustrated if other person has different opinion.  Understanding is demanded from both ends. You must reciprocate love if other is valuing you and making efforts to understand you.
