Is it possible for a guy who has your cell phone number able to come find you?

Please be serious about this question because I'm really worried I gave this guy my number that I've been talking to on a chat room on and now he's been calling me during school and texting me and saying really weird flirty things that make me feel uncomfortable. I want to tell him that we are just friends but I feel like he will get mad and tell me he's going to do something horrible. Do you think he can find my address because he has my cell phone number and is there a way to block his calls or make it say for him that its disconnected? (I just don't want to bring my parents into this because I know it will worry them too much)
