Responsibility vs Obligation

We need to communicate with each other because we can't read the other's mind.  However, what if the other side has decided not to disclose parts or most of his capacity to the partner? I personally think there is no absolutely right or wrong on this matter since everyone has his/her motivation behind.  Some people just simply tell the other half every little tiny detail thing such as the time and among of poo everyday (excuse for being disgusting! lol). But some people don't think it is necessary to communicate much as they may have different objectives in a relationship.  I interpret communication is one of the ways to establish and achieve goals within a relationship.  

Most of the time, people are perhaps situated in different stages of the same relationship.  One may reach faster because he has a bigger leap and a further vision to life.  The other may reach slower because he may just focus on the things ahead.   If the gap is getting bigger while the commitment is not strong enough, perhaps, "responsibility" is not too applicable. Sadly speaking too, when commitment is no longer valid, perhaps, there is no such thing we call it responsibility.  I would say at moment, responsibility is more likely coming from courtesy and respect. 

Here also comes to distinguish "responsibility" and "obligation".  To my understanding, obligations are musts while responsibilities are "supposed to's".  For me, I would not just be responsible, but obligated myself to a relationship if I have found a right match.  At the same time, I expect the same from the other.  But of course, I will need a con-sense from the other party as well as it is meaningless to be engaged blindly.  I won't force or blame the other half as we are formulated with different values and backgrounds.  If he doesn't agree, there is no point to continue.  Maintaining balance of contribution in a relationship between the two is not something we cannot refer from the books and manuals.  Obviously, we cannot just contribute but we shall also expect a fair return, more like on the spiritual side, from the other half.  The interactions and sparks are all important elements to make a relationship to renew and grow.  In that stage, obligation may replace responsibility.

I am not a buddhist.  But I do agree every matter is composed from causes, and consequences would always follow.  We may not see and identify the consequences linking to the causes immediately.  There is always a karma.  Those people who choose to run away from all the immediate problems.  Don't worry, they are relieved in a short while.  Bigger sufferings can happen on them in the later course of the life.  Life is short but not too short.  If the suffering is severe, even the life lasts only for a few minutes, it would be miserable enough.
