I have one contact that no matter what I do when I text her it changes to her email address. I select her phone number and one or two texts will work but after that it changes and goes email again. I've never even saved her email address. I'm assuming it's their because if her Facebook contact info. I have completely deleted the contact and all messages/history, unfriended and the created the contact with just her phone number then refriended, BUT IT STILL DOES IT! I'm seriously frustrated. It only happens with this one contact.
