Englishman,
I (purposely) read that as you asking for your wife and her friends. If you meant as the others here understood, that you’re having that issue between you and your wife, I consider that an emergency. You should speak to a smart person who knows you personally. A wife doesn’t have to be your Chavrusa or fellow philosopher, basket ball player, hiker, or classmate. You can learn to (re)appreciate the difference of perspective. Something like this may change on its own, but why risk it?
In a friend you are looking for someone that you can do certain things together. But nobody is actually a shallow person, although their choice topics might not be your choice.
