What I have to do to share my music wit my wife??

Hello stoefler,

To share your Apple Music subscription with your family you'll need to set up Family Sharing. You can learn how to do that here: Set up Family Sharing - Apple Support

Once you have Family Sharing set up, you'll need to have an Apple Music family subscription. Get an Apple Music family subscription - Apple Support
