If there is a problem there is a cause...
In your case, I think you are really in a mess, if you don't put things on it's right way then most probably you will end up in a very stressful and painful situation. Like most of the members have already said here, her actions is not likely of a person who is inlove. Get it sort out as soon as you can, and sorry to ask you, you married a girl without even knowing her past?
Now that is too late to be answered. Clean the mess and make her realize that you are not a stupid white man.
No one is to blame but yourself...
