How to prevent find my iPhone from finding you?

I'm 16 and I live at home with my abusive father. I really don't feel safe anymore and I want to go stay at my aunts house for a couple of days but my dad knows how to use find my iPhone and he uses it to track where I'm. I can't leave to my aunts without my phone but I don't want him to track me down and harm me or my aunt or her small children. Is there a way to prevent find my iPhone from finding me?

Turn the feature off on the phone.

#1, you WANT your phone, you don' t need it.
#2 he won't look for you your aunt's house?
