If responsibilities, appreciation and commitment are there, then a relationship can live longer but if you really want to have the warmth of divine serenity in a relationship of love then you must stop thinking logically and practically and love someone selflessly without thinking about his or her caste, age, complexion, job, money etc. I guess. Most of us probably fail in the latter one. Of course then we are ‘not called losers’ in our society but if we fail to think practically, logically we are ‘definitely going to be called losers’. However, the concept of love is ambiguous enough to discover because when you discover you may either have it or lose it and there wouldn’t be a middle path to choose for. So, it’s a riddle and of course a beautiful feeling of being connected with someone.
