Yes. If I had a better poker face, I would be doing this over and over. I knew a Russian mail order/internet bride who did this when she realized the asshole who bought her over was nothing but an impediment to building savings (and her college education, which she paid for herself) and her career. Her hubbo, who refused to learn Russian and didn't accidentally learn more than a few common words despite being around the language a lot, ate it up. His family thought she was such a good wife, cooking his favorites all the time. Fortunately, or unfortunately depending on your point of view, he was caught fucking another piggy from down the street and she got out of that situation with a smaller payout. So yes, I think it does happen.
