如果你有钱，这种事在美国太好办了

个人认为你的故事漏洞颇多，不过愿意给你benefit of the doubt. 如果你有钱，这种事在美国太好办了。赶快雇一个好离婚律师及翻译，把你的情况讲清楚，要回一半财产没问题。你婚前所签文件因你不懂英文又无律师代表，一般来讲是无效的。You can argue for fraud, duress, etc. You may even have your marriage declared void and get back ALL of your money if you are lucky. A good lawyer can do it, trust me.
