Why do I receive messages sent to my wife"'s iPhone?
My wife and I each have an iPhone. Occasionally a message from a friend of hers will appear on my iPhone Messages. Sometimes the message doesn't go to her phone but just me. The senders must believe they are sending a message to her phone. I bought the phones at the same time. If a friend of hers receives a message accidentally from me it appears to be sent by my Apple ID. I would like it that messages I send to my friends don't end up on her phone and messages from her friends don't end up on mine. Thank you if you can help.
iPhone 5, iOS 6.1.4
