Wow, time for a restraining order! I really suggest having all your electronics looked over to make sure he didn't do anything to them, checking for cameras, and changing all your locks. Getting a self defense weapon of some kind would also be a good idea. If you live in an apartment complex, inform the manager that he shouldn't be allowed in the building anymore, and explain why. Otherwise, talk to your neighbors and ask them to let you know if they see him around the property. Unfortunately, if he's taken any pictures of you, I don't know of a way to make him get rid of them, unless he does something illegal with them, or you KNOW he has photos he took without your permission in a place you have a reasonable expectation of privacy. Also, you should talk to your mutual fitness first- depending on what kind of stalker he is, he could try to either paint you as the villain, get inside your friends' heads and make them think you are over exaggerating, or potentially target them. It might also be a good idea to get counseling- handling a stalker is very emotionally and mentally stressful, and that's when the person has been lying to you the last several years. He also could have done stuff that damaged your ability to gauge what behavior is appropriate, your ability to reality check, and so on. I hope this advice is helpful to you in some way.
