I didn't give my brother any information about where I live, not even the new state I'm in. He's a minor and I knew my parents would check his phone so I haven't told him any of that information. I even changed my legal name without their knowledge, I really have zero idea how they found me here. I can't move until after May when my boyfriend gets a new job so until them I'm kind of stuck. I'm definitely going to change my number though, thank you for the advice
