NEVER, EVER share an Apple ID with anyone - family member, significant other, etc. That is only one of the many problems sharing can cause.
Apple IDs are personal; they shouldn’t be shared any more than you would share a toothbrush. If you share an Apple ID with someone else many bad things will happen. Each user should have their own Apple ID, then you can create Family Sharing→What is Family Sharing? - Apple Support. That way you can share what you want to share and not share what you don’t want to share.
It is OK to share an Apple ID among devices used by one person, such as an iPhone, an iPad and a Mac; in fact, it is a very useful thing to do. But not between devices used by different people.

And here is guidance on how to fix the situation→How to “unshare” an Apple ID - Apple Community
