iPhone 7, iOS 11.1
The data is being combined because you are sharing an Apple ID. You should each have your own Apple ID. You can then use Family Sharing to share items.
Family Sharing -What types of content can I share?
Family Sharing - If you don‘t see your family‘s shared content
Family Sharing - purchases and payments
Family Sharing – share iCloud Storage
Apple Watch Activity Data
