Here is how you can remove a friend from your friends list:  Apple:
- Go to the 'My Profile' Icon in the bottom, right hand corner
- Tap on "^" arrow on your main profile image
- Go to 'View Friends'
- Next to the person you want to remove, tap on the icon next to their name that says 'Friends'
- A menu will pop up that says 'Unfriend (name here)'. Once that is chosen, they will be removed from your friends list
Android: 

- Go to "..." in the top, right hand corner - Go to 'My Profile' 

- Tap on the "^" arrow on your main profile image 

- Go to "View Friends" > Next to the person you want to remove, tap on the icon next to their name that says 'Friends' > A pop up will appear asking if you want to unfriend this user. 

They will then be removed from your friends list.


And for a little piece of mind, they will not receive a notification that you have unfriended them
