Why did Edna marry Leonce in The Awakening and is he a model husband?

In chapter 7 of the novel it is revealed that Edna
marries Leonce on "accident."  That seems like a rather strange idea, but as the
paragraph follows, the situation becomes more clear.  Edna was actually interested in
another man but Leonce was deeply in love and "presssed his suit with an earnestness and
ardor which left nothing to be desired.  He pleased her; his absolute devotion flattered
her."  Edna was pleased by the attention of this man partly because she didn't have the
attention of the other man.  She also thought they perhaps they had some things in
common.

The most forebdoing comment in the paragraph though
is what follows.  It is revealed that Edna's father and sister where very opposed to
Edna marrying Leonce, who is a Catholic.  Edna seems to take great delight in doing
exactly the opposite of what they expect, so she marries
Leonce. 

Another reason for marrying Leonce is that Edna
thought then that by marrying a man who worshipped her she would "take her place with a
certain dignity in the world of reality, closing the portals forever behind her upon the
realm of romance and dreams."  She thought this marriage would suit her and that she
could maintain an emotional distance, but still have her place in the
world. 

These revelations are important to an understanding
of Edna's character.  She didn't one day decide she wanted out of the marriage and her
responsiblities.  She has had the seeds of discontent and a unique sense of herself
since her childhood, and that explains much of her current attitude and
behavior.
