We have been sold a lie. Marriages is not about happiness. I would argue marriage is not a source for happiness. The fact is life is full of suffering and hardship. You get married so that you don't have to go through that hardship alone.

Imagine life's hardship as an ocean and you are floating on it on a raft. You either float in it alone until you die or have a wife and kids on that raft with you. But among yourselves on the raft, you could also have conflicts and disagreements but you are not alone.
