very sypathetic! whatever happened has happened, including whatever mistakes you have made in the past as marriage is concerned. I think there is no need to look back and feel sorry for yourself or anything. just move on to the remainder of your life: only half way through yet! take care fo the children as much as you can. It will be hard, but you will get over it over time: anything, everything.
i am no racist but honestly i would not dare to marry a white or black woman. it is ok to date them and most of them are actually fine gfs. they are just not going to make a good wife. besides culture difference between asians and them, the court system here is way too biased. good luck guy, i think you need to hire a better attorney.
Look at the bright side she now has much less control over you, and you are in a much less degrading situation. If possible I'd suggest try to get more time with your children and try to participate more in their lives. Watching them grow up may make you feel better. As for your ex-wife and her family, you should stop apologiing... it's their problem that they value money over love.
