I could be wrong... but I have a similar use case to share with my girlfriend.
I did a bit of googling a couple of years ago for a solution. The one I came with was to add our Google accounts to the samsung calendar app. That way we can see each other's shared Google calendars.
In terms of the samsung account I did not find a solution.
When I create an entry to my calendar, if it is personal to just me then I add it to samsung account and my girlfriend doesnt see these.
If it is intended to be shared with my better half then I add it as a Google entry. She can then see this as we share with each other through Google calendar.
It works for us.
