My iphone 5 sends iMessages and texts like they aren't from the same phone?

Ever since I upgraded to my iphone 5 I've been having this problem. My husband has 1 contact in his phone with my number, but he always receives my iMessages and text messages in different folders. My name and number will be on both, but they always go to separate folders. Like in his messages my name is on two different text. They aren't duplicate text. I have no idea why it's doing this. I've tried disabling and reenabling iMessage, but nothing changes. Can anyone tell me why it's doing this?
