Ex boyfriend sent me a "friend request" on Facebook

Anonymous
Like the title says, my ex boyfriend sent me a "friend request" on Facebook. Our break up was about 9 - 12 months ago and was not very civil so I have no interest in being friends with him. Should I just ignore the request, or would it be okay to tell him that I've moved on, so he should do the same and that he is mistaken if he thinks I would want to have any contact with him again?

I did end up adding him. He asked me to hang out, I declined because I have a boyfriend and thought that would be inappropriate. He didn't get his way, so he started being really nasty towards me. Learned from that mistake. Thanks everyone for your input, though!
