Why do my iPhone text show up on my iPad and how can I stop it?

You’re sharing an Apple ID. This ends badly. These texts are one of many things that will be intermixed among all devices sharing the Apple ID. You’re quite possibly sharing passwords, web histories, notifications, two-factor codes, and other details, for instance.

How to untangle this from some earlier threads, and how to set up Family Sharing:

Apple ID - Apple Community

Stop sharing Apple ID with wife - Apple Community

Set up Family Sharing - Apple Support

Got to settings, messages, scroll down to Text Message Forwarding and toggle off iPad. It’s happening because both devices are sharing the same Apple ID it appears and text forwarding on. Unless you’re trying to describe a different situation

No guarantees, but please try the following:

On your iPhone.......

Tap Settings > Messages > Send & Receive

Make sure that a check mark appears only next to your phone number

On your wife's iPhone......

Tap Settings > Messages > Send & Receive

Make sure that a check mark appears only next to your wife's phone number

Please report on your results

Stop sharing an Apple ID.

Apple IDs should never be shared, Your Wife should have her own Apple Id separate to yours.
