i’m not great at explaining however once you’ve added the user as a friend, head to your main ij page and on the left hand side you’ll have under the heading of friends ~edit friends group. here you can make a custom group and add the user to this. then at the bottom of the page you’re posting the entry of you have the option to select who you’d like the post to be visible to (friends, private, public, custom); select custom and you’ll be prompted to pick one of the groups you’ve made. click to select whatever you named the custom group you added that user to and once posted only they’ll be able to view it. hope this makes sense, i can post screen shots later but being on a phone is limiting :(
