Charlotte Lucas is the character that most closely matches the women of that time. Previously women had to for the duty ahead of love, they all hoped to fall in love with her ​​husband after the wedding, I like to think that this happened to almost all and that love was reciprocated. 

We have the freedom to choose love but we don't appreciate it.

I wish Charlotte Lucas had found a man who really loved but our beloved Jane Austen wanted to show her reality through it.
