Hello JustinLoucks,
Thank you for using Apple Support Communities. It's my understanding after updating to iSO 10, you're now receiving your husband call history. I can surely understand how it would be concerning to unexpectedly see your husbands content. I am happy to help get this resolved with you.
Your Apple ID should not be shared with anyone else. It provides access to personal information including contacts, photos, device backups, and more. Sharing your Apple ID with someone else means you are giving them access to all your personal content and may lead to confusion over who actually owns the account. To share iTunes & App Store purchases, photos, a calendar, and more with someone else, try Family Sharing, iCloud Photo Sharing, or other easy-to-use sharing features.
