Several times during this 3-4 week period tried to find out what the problem was and either one or two things would happen 1) She would deny that there was a problem and that everything is normal or 2) She would get mad and switch it around and say that I was the problem! What can I do to find out what the problem is and how to fix it?

I would try to find out exactly what you're doing that's upsetting her so much. If she says, "You are the problem," ask her to be more specific about what it is that bothers her so much about you. It's probably more than one thing though. She may be upset about a lot of things. Try to be understanding and don't get defensive.
