How do I keep away from my mom?

I moved out 2 weeks ago, and my mom will not stop with the pestering. She calls me, She begs me to come home, begs me, begs me begs me. THen she starts nagging, and nagging, and nagging. I have a secure home environment, I'm going to school, and I have a job, So what in all reality can she do? I've talked to her about moving out, so it's not something I did on impulse, and she keeps lying to me! I know because she'll say something is wrong at home, and then at school, I'll talk to my brother who says there is no such thing is going on! Help!
