Follow-up on my facebook conversation: my life is at risk???

Hey yall. So the guy that I recently posted a journal entry about (Jesse) who said all those terrible things to me on Facebook? He's now texting me and he started telling me that no one loved me. Then he threatened to come to my house and rape me and hurt me. I don't know why I'm posting my business on here except for that I recently lost my best friend Chelsea because she really wasn't a very nice person, and I know that Mibba-ers are a lot nicer than that. I'm not too sure what to do since he knows where I live and such...:/ Comment with advice?
