How to stop my dad from tracking my phone?

I have an iPhone 6. I'm 17 years old, and when my parents got a divorce a year ago I moved in with my mom because my dad had been mentally abusing me. He still does it over the phone, but I can deal with it as long as I don't have to be around him. I recently went back while he was away to get the rest of my stuff from his house. He will be getting back from his trip today, and I'm scared of what he will do when he gets back and sees that I have completely moved out. I just found out he can track my phone with a parental setting or something, and o wanted to know if there's anything I can do to make it so he can't find me. Will turning off my location help?

Why Did He Act Like This?

We were trying to get back together(i have been the one chasing him and he was responsive but still cold and kind of meanish saying he doesn't love me but has some feelings and will take time to get comfortable to be expressive) and were fighting again. Said the worst things to eachother and he said to move on from him and go and date the guys that are after me. When I finally said ok and sent a fb date invitation from another guy. He said fine go get lost. Then like 5 hours later he texted on viber( i blocked him on my phone) like shame on you i can't believe youre going out with him. If you go out with him I won't ever take you back( he was telling me how he didn't want me and now this)., he sent a screen shot of his iphone text inbox the top one being saved as Anna saying I miss you(i'm wondering if he made a fake number and texted himself and saying i wasn't the only one playing those games and how that's why he wasn't paying me
any attention) and I blocked him. He messaged on whatsapp an hour later saying shame on you and i didn't reply then 20 min later texted with a different number saying shame on you and i didn't respond. He really didn't want me and was cold towards me and saying such mean things. That was 2 days ago and today was my date.
