Friend suggestions gone wrong

It would be nice if Facebook had an option to tell them WHY you don't want to be friends with someone. 

Dear Facebook, STOP suggesting my ex boyfriends as friends. Trust me, there's a reason we aren't. There are two people that you have been suggesting to me for years. Seriously Facebook, give it up. If you had these guys as exes you would feel the same way. There should be a "click here if you never want to see this persons face again" button. Thanks in advance!
