My iPad messages can be seen on my sister's iPad, too at her house.

I connected to my service at my sisters house on her business iPad. I didn't have mine available and wanted access to my contacts, not sure what I did? Now any messages I send or receive on my private iPad can be seen on her business iPad, how do I disconnect that.?

Settings>Messages>Send&Recieve

Here you can change which e-mails and numbers are used to send and receive IMessages. Chances are you are you have the same e-mail set up on both iPads. You can change these on other applications in settings if you have the same problem. Hope this helps!
