How do social mores intact and influence people on their perception and their relationship?

For me, all of us have our own perception in life,but now a days because of our technology and social media, many of us are change our behavior and attitudes even our perception in life. For example a religious influences,we different belief and faith ,many religion have their own ways on how to handle their members in their faith,even in choosing someone will be with you forever or to be your partner in life. Some religion have their own policy or requirements, to to choose who will be the person that be a member of their religion. Some families are influence in their religion ,specially christian family,but because of social influence their are not anymore intact ,some of the members of the family are have their own belief that influence of other organization are much better than they have because of this we must be intelligent in our life specially choosing the right behavior and attitudes because whatever we did in our life our own family will suffer.
