See, race does matter. If it were as unimportant as eye color, you wouldn't have "one more issue" to deal with (namely, her parents secretly wishing their daughter could marry in her race). It's a natural desire.
Not saying you wouldn't have any other problems, but I always say, "Why add one more problem?" Life is difficult enough. Try to go WITH human nature when you can. There are so many ways you have to fight it.
That's what St. Paul said -- "inasmuch as it lies with you, be at peace with all men." We have to oppose the world and our neighbor on so many things touching on the Faith -- why be at war with him about petty domestic issues?
As for your case, I can only pray for you and agree that you're pretty much in the right. Yes, those things are messed up: the worldly atmosphere, TVs, non-acceptance of you by your in-laws because you're "outside their race", non-docility of your wife to you (instead of her brother), etc.
I would point out that many problems aren't solved by a pill or a scalpel. Think of a man who is depressed by his state in life. You can feed him pills to alter his brain chemistry, but does that solve the root problem? No. He's still "a failure in life" and that is the real cause of his depression. His brain is not malfunctioning. Now if you could convince him that he is not a failure, then you might get somewhere...
Likewise, many problems in men (as in, mankind) are spiritual or psychological.
She generally doesn't listen to you about the marriage debt? That's pretty serious. Her relationship with her family is also a factor. She seems to have emotional/psychological issues, like she's a 10 year old girl inside wanting to go back home to be with mommy.
Mother in laws, or in-laws in general, can be bad news. That's why traditional cultures believe that you're marrying the family, in a way. That's also why so many races frown on intermixing nations and races. You're basically asking a ____ family to be super close to a ____ family. If they fail to become close, you have a divided house, with him preferring his family, and her preferring hers. How is that good?
Now in your wife's case: did she ever intend to be a normal wife, giving herself to you as in a traditional marriage? Having all the children God sends, and knowing what that entails on her part? It sounds like she had some kind of immaturity and/or psychological issues.
Now immaturity doesn't automatically imply annulment -- speak to a priest.
You obviously missed a LOT of signs during your courtship. As for right now, I'd speak with a traditional priest. It sounds like you've got yourself in a doozy of a situation.
