Hi daryn147,
I want to help you with the sharing options you're seeing.
The intelligent suggestions you see aren't showing a particular person every time, it's part of the suggestions that use recent behavior to suggest who you might share to. If you message with someone repeatedly or share pictures to someone in Mail, that will be suggested.
There's no way to remove this feature from iOS13. The rest of the sharing menu can still be used to share to someone else that isn't suggested.
You can read more about the new iOS 13 features here:

If you have any feedback, you can leave that here:

Thanks for using the Apple Support Communities.
