Marriage Relationship into Family Definition

When I listen and watching the movie or drama in middle of way containing marriage element that a priest conducting holy martimony inside the church, the commonly we may hear is; "will you?" WILL YOU, WiLL YOU or will u?
The to-be husband and to-be wife may said, I DO? What if some of them say I DIN'T?
I assume the great episode of the real movie may begin again inside the church.

When the both bridge agreed to married and now become the real and 'certified' husband and wife in union of one, the family will build in the same time. Having a child or children.
But now my main concern is the child or the children now are growing. The situation change when both "I DO" couples regularly argues and querrel each others and seem to break the relationship and collapse the family.
Everytime arguing and querrelling in front of the child or the children, they just simply sit and listen. Most are sit/stand, listen and watch.

HOW DOES THESE/THIS CHILD/CHILDREN FEEL?

It is a good examples as the children parents set and act such 'drama' of conflict in front of thier children? Particularly the young teenage children? Very worse if some of the child have need to be the intermediaries to express thier opinion, to follow this or that, to go to right or left and so forth.
ONe common reason I have heard and experiencing is the economy and financial matter. The very and very common one. Some say they regret to have children or child because they are stupid and stubborn, or because they are ugly like a pig or chicken or a goose.
HEY.........WHY SO DARE TO SAY SUCH THINGS?
Why this have need to happend in the family? If the parents regret to have a burdening TO HAVE CHILDREN WHY THEY BORN US AND BRING US INTO THIS SITUATION? WERE WE ASKED THEM TO BORN US INTO HERE AND UNTIL TREAT US AS A PIG OR GOOSE?
WHY???

Some family were broken and both parents were splited and separated due to unknown course. WHY? What the children feels over this matter? What if when they saw or see other happiness family sit and stand together but they just again sit, listen and wondering?
They need to leave thier study in the fire bush, and go to work and carry the heavy load in thier shoulder just for the sake of getting survive-for an inch of rice and sloves.
Some society have seen they as rubbish and as sting stools, have no choice, go to snatch and find other entertaiment or approaches.
Again, WHY??? Asnwer: TO carry thier parents sins and nailed in the cross? Chope your head!!!

NOW, those incident of bitterness have past and go throught everyday. Some may success and unsuccess. Some become the brightness and some as a darkness. Some become a sweet of honey and some may as poison of a prey.

Can we stop this as a light and favor generation and to let our next generation to be good and healthy? Can we decrease such conflict in our life? Can we think first before we let thme landed in this world land of blood and sins?
CAN WE?
