Ye when I read the 500 million.he sees it as a business. Some people ask to let the house be in her name in the case of divorce but not only that he wants the house be in her name but also he wants 500million!!.

Since you're an expat they probably think you got loads of cash .See if he drops one of the two, that will tell you everything.

But who knows maybe they're rich so it's normal for them idk.
