Is Mr. and Mrs. Bennet's marriage happy or unhappy in The Pride and the Prejudice?

I feel that they are both basically good people who have their flaws and are not at all suited to each other. They married when they were very young, without giving much thought to the consequences, and are now paying the price. Mr Bennett tends to mock his wife and younger daughters, and pays them little attention. Mrs Bennett occupies herself primarily with marrying off her daughters, and often embarrasses Lizzy and Jane in public with her shameless attempts to throw them and their sisters together with rich young men. She is also inclined to fancy herself of a nervous disposition, which is very little help to her family in times of trouble, and is too indulgent towards Kitty and Lydia.
