Yes, we filed the I-765.

I'm planning on trying this. I think it's the only option I have left at this point.

Hmm. Most of the posters have contradicted my points, although none has actually argued against them.
Remember that, as some have said, you cannot change her. You can encourage her to change, and she can change, with a lot of arduous work. She may or may not change. What's it to you? Did you marry her considering her like a dog? Of course not. You didn't sign a contract with her, you made a commitment to her. What I love about Americans is that (most of the time) they consider there words and there commitments and hold fast to them even though it hurts. I miss that so much about the US and believe that such honesty and dedication is what made America the great nation that it has become. Let's hope things don't go farther in the other direction than they already have. I am going against the grain of what almost everyone else has said here, but: Be a man. Honor your commitment.
You know that a lot of the posts here are dense. How could your wife be an expert in fraud but at the same time be conned into getting on a plan and dumbed in Thailand? Maybe there are some things that you haven't revealed, maybe not, but you are her husband and if you are as honest and objective as possible, I'm sure you can judge her sincerity better than anyone else in this discussion.
Were you happy about signin the I-864 when you were engaged? I'm sure you were. Perhaps I'm going to far by saying this, but isn't it possible that at some point the signers of the declaration of independence which they hadn't signed? Thankfully they decided to stick it out.
Look for a Biblical church near you and see how you can change and how your wife can too.

This is a sad story. Here is my advice, since you've asked.
First of all, VJers, like most of mankind, are disappointingly selfish: "RESPECT+TRUST+ACCEPTANCE+COMMITMENT+CONTENTMENT=Love," what a ridiculous fallacy. Try this one on for size: "Love=RESPECT+TRUST+ACCEPTANCE+COMMITMENT+CONTENTMENT+etc. (1 Corinthians 13:4-8a)" Love is not something given as a reward for good behaviour, such thinking is the reason less than 1/2 of all US marriages succeed. Love is a commitment. If you are committed, here are a few things to consider.
1) Unfortunately, I think you are totally right about the poverty mentality. I have lived nearly 3 years in a third world country and it is clear to see that millions--no, billions--of people in the world have no one to blame for their poverty but themselves, or maybe the devil, or Bush, or Obama...Yes, what you say is true, many people are raised with cultural thinking that is utterly destructive (not to say that US cultural is that great, although it is somewhat conducive to affluence). Here is the good news: your wife can change.
2) Your wife, you said, mentions "50:50" a lot. Again, this is a terribly selfish, humanistic idea (way to go, western society!). "50:50" is for contracts, not for marriages! Marriage is a commitment of "100:?". It is not a matter of getting what you want out of it. Mind you, if your wife is unfaithful, you are justified in divorcing her. However, as long as you are married, you should strive for "100:100." Simply put, both spouses selfless love and build up the other, without thinking about themselves. This is how good marriages work! Here's the good news, you can change your #, and if your wife decides to, she can also change hers. But your commitment to love cannot depend on how much she gives. That is not love.
3) Your wife does not seem to have solved her past problems and has come into the marriage with faltering commitment. This is dangerous for your marriage, and causes a lot of suffering for you and for your wife, even though hers is self-imposed. Good news: your wife can change.
If you make and your wife make a decision, based on the right principles (i.e. selfless love), to change, all of these problems can be solved. Do you consider yourself more mature? If what you have written is true, it seems that you are much more mature. Then why don't you initiate the process? If you are going to end this marriage, don't end it by being selfish. Tell her that she needs to make a 100% heart and soul commitment to being emotionally and physically faithful to you. Tell her that you want to help her to learn how to leave her past and heal from it. Tell her that you want your relationship to be bulletproof, that you will be by her side as you both learn to love with actions and discipline, not just with feelings and words. Want some good principles? Here are a few: Matthew 22:37-39, 1 Corinthians 13:4-8a, Ephesians 4-5.
Just remember, the reformation that changed northern Europe began with the Bible. You and I don't live in poverty simply because some men were willing to give their lives in order to give the common people the truth of God's Word, starting the sequence of events that led to the greatness of Europe and later America. Look at a map. Northern Europe and parts of the world colonized by its inhabitants = reformation mentality. Southern Europe and the rest of the world = third world countries. That's my two cents. Best wishes.
For better or worse, till death or infidelity do you part.
