Hi and Welcome. My Name is ***** ***** I look forward to assisting you today with your question.
Did you restore your husbands backup to your iPhone from your computer or did you restore the husbands iPhone to factory settings ?
If you have restored your husbands's iPhone to factory settings, then do this. Connect the iPhone to your computer and open iTunes. In iTunes, select the iPhone (at top left). Click Restore Backup button. From the list of backups, find your husband's backup and click Restore. If you can't find the backup of your husband's phone there and if everything from his phone is already gone, then you can attempt to restore that device from iCloud. Go to Settings > General > Reset and tap Erase All Contents and Settings. After erasing, this will bring setup screen. While setting up, click Restore from iCloud option and this will restore the most recent backup to his phone from iCloud if any available.
If you restored your husband's backup to your iPhone from iTunes and if everything on your iPhone is deleted and replaced with his info, then you need to restore your own backup to your iPhone. Connect it to your computer. Open iTunes and select your iPhone. Click Restore Backup. Select your backup point.
If you don't see your backup, then erase your phone from Settings > General > Reset > Erase All Contents and Settings. Then restore from iCloud while setting up.
(If you want to restore your iPhone to new, then do the erase it from Settings of device or restore it from iTunes on your computer). Let me know how it goes please.
