My and my husband phone been hanked he get all my stuff and I get all his stuff how to stop it
Sorry for my reply.
It sounds like your phones is synced (?!); Does it possible that there "in use" some default features under pnones (iOS? Android? Windows Phone? other mobile platform?) about sync-options (or connected devices)?
Or some software (as cloud-storage or sync-service)... which can be with "one account" for both phones?
Or you mean something else (as more suspicious view of situation)? Maybe you able to provide some more information (like which phone platform; what kind of stuff there - media? phonebook?) - and maybe there will be more good advices/suggestions from other community users.
Are you sure you haven't inadvertently swapped phones?
