Are the children can be the reason why a couple keep thier marriage vows?

well in a perfect world...marriages and love would last forever. but unfortunatly they dont, whether or not the couple have children...they can still fall out of love. a lot of married couples try to "stick it out" for the sake of the children...but more often than not, the children would be happier and less stressed if the couple would just get divorced.

Having children does not guarantee a long lasting relationship, though in couples, the kids play a big factor/reason why they stick together. However, it is not good to make the children the only reason why couple stay together. Let say a couple agree to stay together but have separate rooms and they often have ugly fights. I don't think it still good for the kids.
