I'm new to the iOS world and am really getting into it. I have an iPhone 5 and the new iPad set up on the same Apple ID. I want to be able to let my wife send iMessages from the iPad to my iPhone during the day and vice versa. The problem I'm having is that when I send a message from my phone to my iPad, it creates a duplicate message on my phone or vice versa. How can I adjust the settings to have only one message created on the receiving or sending device? If I can do this, will I still be able to share iMessages across all devices?
