In Madame Bovary, how does the contrasting perspective in the Bovary marriage correspond to the treatment of reality?

The Bovaries are a couple with conflicting personal issues
that do not enable them see life for what it really is. They, within themselves, are
prone to fantasize about their realities. Then, as a marriage, they allow for the
fantasy to exist by recoiling back into the comfort zones of their
imagination.

In the case of Charles, he knows exactly here
he is coming from: as a child he was bullied. Growing up, it was a challenge for him to
learn. As an adult, he had to overcompensate her lack of energy for life and did his
best by trying not to get into any kind of trouble. He was a purist in terms of bland
determination.

The only time when fantasy struck Charles
was when he met Emma. In her, he saw all the passion he had lacked from life, because
she, herself, was quite a passionate spirit (albeit not to him). In his fantasy
marriage, Emma is a beautiful woman who does her best as a wife even if it is the
minimal.

On the other hand, Emma also married Charles under
a fantasy spell. She had not yet awoken to the passionate adulthood that awaited her and
Charles was ill-suited for her tastes. She would read French novels and wish to be an
aristocrat with money. She began then to try to fulfill her dreams by taking lovers and
developing an obsession with money and having things that she cannot
afford.

When reality struck and she found herself helpless,
bankrupt and left out of all of her lover's lives, she could not help but killing
herself, still under the notion that she was deserving of something
better.
