Facebook and Twitter – Are Your Friends With Your Ex? [Poll]

I have to know -  do people keep their exes on their friends list?

I have exes on my friends list, but I'm actually still friends with them. (it's not because I want to face-stalk them) The exes that I don't get along with are not on there, they were deleted at the time of the break up.

What do you do??? I have to know take my poll below....
