I'm typing this from memory, so I hope it's all correct.
You will need a second Oculus account for the new Go. Set up the new Go with the new account. It's easiest to use another phone - so use your wife's but you can log in and out on the same phone if you want.
From your headset, add the new headset account as a friend. You might have to have a Facebook account for each Oculus account. I'm not sure about that.
To add friends to your Oculus account on your computer:
- Open the Oculus app on your computer.
- Select Friends from the bottom-left menu.
- Click Add Friends and search by someone's username or first name and surname to add them.
To add friends to your Oculus account from your Oculus Quest or Go headset:
- Press the Oculus button to bring up your bottom toolbar.
- Select the People menu from the bottom toolbar and choose Friends.
- Select the Add Friend icon at the top of the Friends panel and search by someone's username or first name and surname to add them.
To add friends to your Oculus account using the Oculus app on your phone:
- Open the Oculus app on your phone.
- Tap Friends from the bottom menu, then tap Add Friends.
- Search by someone's username or first name and surname to add them.
You will have to buy Wander for the new headset. Yes, you have to pay for it again on the new account. Install Wander on the new headset. Both log in to Wander on your respective headsets.
You can then invite your wife to a Wander session - you will host the session and control where you visit. You click on the multiplayer icon with three heads. It will ask you to create a room. When you do, you can select 'Friends only' so you don't get random people joining you. Send an invite to your wife. She has to accept the invite. And away you go. Wherever you travel, she will follow.
Of course, she could host the session and you can follow her.
