Please don't take this the wrong way. I myself am Asian and understand a lot of the cultural pressure for success. It looks like she hit a mid life crisis. Her sudden resignation of her job to me shows that maybe she found out that 60 hour weeks and dream houses was not what was going to make her happy. So instead she now wants to live a "carefree fantasy life". There is nothing wrong with that. The problem is that she failed to communicate this to you (or you failed to get her signals). She will most likely claim she tried to let you know. The other thing is that she is also leaving you stuck with the house and other expenses. Very irresponsible, but in a way it feeds her fantasy, right?
She is currently re-evaluating her whole life, and that includes you. She probably even blames you for most of it.
Ok so she has this fantasy of what life can be without you. So what can be done.
1. Accept and validate how she feels. You're not going to change her mind through logic or reasoning just accept it. She wants freedom and is suffering from grass is greener on the other side syndrome. Admit that maybe you don't have the greenest lawn right now.
2. Let's continue the metaphor. Let her go play on the other lawn. Very often the walk away wife will find. That her freedom is not what she thought it would be. Ultimately she needs to decide this for herself though.
3. Finally you need to add some fertilizer to your own lawn to attract her back. Go out there have fun, live the life she herself is trying to live. You might find that she may come back to live it with you.
