The post where you said...
Simply make sure your husband keeps the Apple ID password and username/email so he can continue using that Apple ID.
If you still need the apps etc, then tap 'Keep on iPhone'. If you don't then remove - you can still get back the Data stored using that particular Apple ID/iCloud sign-in, but only via that Apple ID.
*My advice: 'Keep on iPhone' - just to be safe since we're still new with iCloud.
Nx you can proceed to create a new iCloud account, which will require you to create another Apple ID. but as usual, you won't be able to "transfer" any apps from your current ID to the new one.
