Elizabeth, intelligent, has her own ideas.Darcy, born noble, proud, disdainful of vulgar things.Elizabeth ended up with darcy. I think their marriage is happy.Mr. Darcy's pride was once considered natural. Here's a passage from the book:

Do you wish me to rejoice at your humble relations? Do you think I want to toast myself to social connections that are nowhere near as good as mine?Although the words sound sharp and hurtful, I have to admit that this is the truth.

Birth, environment, your family, they how, you can not decide, but there are reasons not to let themselves into vulgar. Even though, poor, even though, the family is always making jokes outside. But what does it matter? You can still develop the character and wisdom of Jane and Elizabeth.Not every good girl can meet Mr. Darcy as Elizabeth can, but I hope she will not be so reckless as Lydia, and blindly enter into an unhappy marriage for a moment's pleasure.Be wise and judgmental. Don't be blind. There will be love to look forward to. There will be Mr. Darcy like Elizabeth waiting somewhere in the future.
