Friend Request question...don't know if just refused or if problem with Facebook?

[pri✍]

Out of sudden there comes X & Y, and the rest, I understand vaguely what are trying to say, so I'll try my best.

When you visit someone's Timeline, someone that you sent friend request, and you see "Add Friend" button, it means they declined your request.
As 4 out of 8 declined you, slow down on sending new friends request, as FB will count that and if exceed certain 'secret' amount within 'secret' period of time, you might get blocked from sending new friend request.

In your Timeline, ie in Recent Activity, you'll see who are your new friends, FB don't inform who declined you anywhere.

To see who you sent friend request & who you're friend with (and the when), you should click your Activity Log that is on your Cover Photo in your Timeline ➤ click MORE on left column ➤ click Friends ➤ there you are, all your friendship information, except for other's declining your friend request, and who unfriend or block you.

Hopefully this give you enough information regarding 'friends' in FB.
