Usually, in your contacts app, there's an option to export and import contacts.
When you export your contacts, they'll be stored on your sd card.
From there, transfer them to your husband's phone and then import them.
An easy way to get to your phone's storage if you have any trouble just plugging in your USB cable and using your PC as a go-between is AirDroid.
Uses your home wifi and it's free in the Play Store.
Hope this helps!
