Restraining order in Georgia?

My ex boyfriend was sending me IMs every time I got on facebook. So I deleted him. Then he started sending me messages over and over cursing at me.. He said he knows that my new boyfriend is at my house all the time, which obviously means he has been riding by my house.. He lives no where near me, so he would be going out of his way to ride by. The day after we broke up he came by my house and was banging on my windows and ringing the door bell nonstop for about 15 minutes. I honestly feel threatened and don't know what to do. I don't want to have to see him in court though. Someone help please.. ?
