How do I remove or cancel a friend request I sent to someone?
The quicker way is actually using the mobile app (if you have a mobile device) and selecting ‘delete friend’…otherwise you could go to the “Activity Log”, located beneath the Cover Photo on your Timeline, on the page that appears go to the list on the left, click on “friends” ( If “friends” doesn’t appear, click “more”) …on the next page all of your friends are listed and you can update your friends one at at time from there.
Below is the official instruction
To cancel a friend request you sent:
- Go to your sent friend requests
- Hover over Friend Request Sent next to the request you’d like to cancel
- Select Cancel Request > Cancel Request
