is there a way that my living aunt can see the memories i've added to familysearch
Your aunt (and any other user) can see memories that you have attached (tagged) to any deceased person in Family Tree.
As long as you have not marked a memory as private, anyone can see the memory, but it might be a bit difficult to find. If you want your aunt to see all the memories you've added, a simple way could be for you to add all your memories to an album. Then you can share the album with your aunt, and she can see all those memories. Of course, with this approach, as you add additional memories to FamilySearch, you'll need to remember to add them to that album.
