There are a few ways to tell if someone deleted your friend request on Facebook. The first way is to check the “History” tab on Facebook and see if anyone has deleted your friend request since you last used the site. If so, you can be sure that someone removed your request without your knowledge or consent. Another way to check if someone deleted your friend request is to look at the “Request History” tab on Facebook and see if anyone has made any requests for friends that you have not yet added. If someone has made a request for a friend that you have not yet added, it means that someone may have deleted your friend request without knowing about it. If you are not sure whether or not someone deleted your friend request, you can ask them on Facebook or in person.
