how to tell them to let go after so long?

I have 2 exes that are kind of stuck on me. I had one who I dated 6 years ago add me to his myspace. I was like ok, we can be friends. The next thing I know he tells me that he loves me still and misses me. The other I stopped talking to in Jan 2008. He got a hold of me in April. I had deleted all social sites and left out anyone who would tell him how to talk to me. Well April this year he was all I love you and want to be with you. Im not into either of these 2. I have a great life Im married and happy. These relationships ended in bad ways. How do I get them to let go of something that isn't going to happen? I just don't know how to deal with these losers or why they are being like this now? What can I do? Ignoring doesn't seem to work.
