I agree. based on what I read, neither Jin Fang nor JRF has good reasons to run off.
Jin ran a homestay business in Portugal(
that's how her good friend Emily met her), she returned to China when COVID hit and Tourism was down.
she is financially stable and a veteran traveler, her parents and daughter love her, Why would she give it all up?
If she wanted to stay in the US, she could simply pay and "marry" JRF, he gets money and she gets citizenship, or the 2 of them could set up a joint-venture then she could get a work visa...there are many ways to stay in US, why would she need to elope? I highly doubt that she planned to become a US citizen and start a completely different life in US at age 47. China is a rising power and has impeccable cities and peaceful society, she is from Guangdong, a highly developed province, life is beautiful there if you have a little money, which she does have.
JRF had served as a navy seal for more than 20 years (if his statement on linkedin is true), so he has handsome pensions or retirement that he wouldn't want to give up. He also has his own business. His love for his ex-wife might have been lost, but her
divorce filing shows that they have minor children, it gives him less reason to go into hiding--well, I presume most parents don't abandon their kids.
