First this is most likely not even "ONE WOMEN" or at times not even a women. Scams from Ghana is a big business. There are large buildings filled with people at computers, they use prepared texts and stories that have been proven to work. There are managers that read over and review communications and suggest things to say. Today you may be chatting with person 1, tomorrow may be their day off and you talk to person 2, but they have all of your texts to review to keep the converstation going. They will take months to sit up a person if it is going along their plan.
The issue I see , this is such a famous scam, been shown on national TV, why will anyone even fall for it still, but they do. And after they do, and figure it out, in a few months you get another email from someone who claims to be in the FBI or some Ghana government, saying that they will be able to get your money back ( guess what for a fee) to file some paper.
The government there cares less, many of the large groups may even control local police.
As for the email address, they have 100's or 1000's of them, change them after one gets too well known And that will not even be a real name of the person.
