]Anne and Captain Wentworth were not going to marry until Wentworth had earned enough money to support them and their kids.

Yes, this is true. Someone also said that Anne probably had some money coming to her so she would not have been entirely destitute in any case. Perhaps I shouldn't have included some of the examples I listed but I was basically trying to show that no matter how bad the possibilities, some of which I believe have come up, she should have been allowed to make her decision without pressure. Thanks for clearing it up. :-)
