If someone leaves you without telling anything

Definitely I agree with you. Ending a relationship without discussing with your partner, the reasons for ending the relationship is a Coward's act. This kind of behavior either from a  man or woman is really shameful and in my view, such acts should be condemned by all means

I  believe in open discussion and put my thoughts on the table. Naturally, I would expect the same from others and will definitely respect one's thought. If there is any contradiction then I would try to clear the doubt and will expect the other side to give me that very opportunity. If I am not told about one's decision openly then I would feel betrayed. 

Better and proper conversation makes a strong relationship as it provides comfortable understanding between two individuals. If any person leaves his relationship without thinking a moment and without trying to continue it with must required conversation with whom he had a relationship then that person doesn't deserve to have any relationship. 

I have a different take on this . For anyone to leave suddenly , either there has to be a solid reason or the relationship has not really been satisfactory or good. If there is communication and a certain level of understanding such a thing is unlikely to happen..

Lack of closure in a relationship is something that can linger forever. Its more complicated and hurtful. people make a way to do what they want. Remind yourself that if the person wants to talk to you, they will.

Open communication should be there but for some relations such your colleagues who try to take advantage of you, I think leaving or taking break from them without saying anything is fine. 

Maybe the best way is to leave without giving any reason. That will help if the person decided to come back and give an apt excuse for his separation.

Open discussions are important in a relationship whether to sustain it with zeal or it end it. If someone leaves without saying, one feels betrayed and cheated. It is wrong. 

But there are times when silence speaks louder than words. So let's look into what preceeded the bitterness in the relationship. Was it ever a healthy relationship with equal say of both involved or did one dominated and other suffocated and chose to walk away

I totally agree with the discussions. sharing of thoughts and reasons can help us a lot. communication slove all the issues and misunderstandings in relations and sometimes helps to create strong relationship so before leaving our partner, friends, relatives we should explain reasons at least onces.

Agree. If there is no communication before moving away, there is always a chance of mis understanding due to which the relationship gets away.

Hence a few views as to why we are putting an end to this relationship is quite essential. It also gives an equal opportunity to both to understand who is at fault.

It also means that people can introspect and what they could do thereafter to improve the current relationship or to take the lessons to the relationships on hand and which are bound to develop in the future.

Yes I agree. One should discuss with a person in relationship before breaking it. Sometimes there are many things in our minds which may be cleared with the discussion 

Agree with you. There should always be open communication between people, as it benefits all.
