Leave her now. The more longer you wait. The more your wealth builds. The more you will lose in the divorce. It's easier starting over at 31 than 38.
Also I would be worried about a baby. If she has a child you will pay more in the divorce. Do not wait. I will file papers now.
If she says she will stop. Be very suspicious. She will probably cheat on you because she wants a half white baby.
I am half white and half asian. I have an asian mother. Let me tell you this. It has opened my eyes Abit cos I get my mother's friends all saying how they wish they could have a half white baby all the time and how they think half white babies are better looking. I heard this so many times by my mother's friends so I do believe some Asian women have a goal /fetish to have half white and half asiam babies.
