How do I delete a phone number associated with iMessage?

Question

My husband bought an iPhone and he set up his Apple ID.  Now his phone number is associated with my iMessage account along with my number.  When someone texts me he gets it too.  When we text someone else they get the text from both of us.  How do I remove his phone number from my account?

Hi Sycoffee,
Thanks for visiting Apple Support Communities.
It sounds like your device may be using your husband's Apple ID. You can check this from the following menu options:
On iOS devices, find out which addresses are enabled with FaceTime and iMessage by tapping:
Settings > Messages > Send & Receive > You can be reached by iMessage at:
Settings > FaceTime > You can be reached by FaceTime at:
On OS X, find out which addresses are enabled:
In Messages, choose Messages > Preferences > Accounts. Select iMessage in the left column. Your contact preferences should appear under "You can be reached for messages at:."
In FaceTime, choose FaceTime > Preferences. Your contact preferences should appear under "You can be reached for calls at:."
Use these steps to unlink your phone number from his Apple ID:
To remove a phone number from an Apple ID, sign out of FaceTime and Messages on your iPhone:
Settings > Messages > Send & Receive. Tap your Apple ID, then tap Sign Out.
Settings > FaceTime. Tap your Apple ID, then tap Sign Out.
This should remove your phone number from other devices using the same Apple ID with FaceTime and Messages. If the phone number is still available on other devices after you sign out of FaceTime and iMessage on the iPhone, you may need to sign out of iMessage and FaceTime on all your devices, then sign in to FaceTime and Messages again on devices you want to use.
iOS and OS X: Link your phone number and Apple ID for use with FaceTime and iMessage
