If you read the news, which I assume you did, you should be aware that her choice was not between a 64-year-old man and some younger guy she had affair with. Her choice was between a women's shelter and a house with a life being provided for. If you have never been to a women's shelter, I highly recommend you to check it out. It is not a place worth you giving up everything in China to come here for.
Even if she is an opportunist to take advantage of the chance to come to the States, she still has all her rights to leave a person she has found out she does not love, just like everyone of us.
Domestic violence is not something you could make out of nothing. Picture in your mind that if she was treated well, would she report to the police?
All I want to say is we do not have right to pass judgment on her, or anyone else, including these Chinese ladies that marry into this country, even if we know all the facts. Because we are not living their life, we are not expriencing their life.
