Parents trying to manipulate me

Me

So I’m 19 and will be 20 soon. When I graduated college I moved out of my parents home came back for a semester but since I have since left and got my own apartment on my own with no co-signer. I pay my own rent, utilities, food, gas, hair supplies, things for my dogs, and etc. Now I’ve been talking to a guy who is older for awhile now. My parents have known about him since when I left their house the first time. They say they don’t like him because they never met him. I’ve been having problems with the apartment I’m currently in and he offered to allow me to come live with him and to help me get on my feet. I plan on taking him up on his offer however I mentioned this to my mom and of course she disapproved since I haven’t finished school yet but I refuse to continue staying in this apartment and don’t have anywhere else to go in the area. My dad sent me a text this morning telling me to call him and I already know what he’s going to say. Anytime I want to do something for myself and want to do something they don’t agree with he tells me that he’s going to take my car away from me or that he’ll take everything away from me in order to manipulate me. It won’t work this time because they aren’t the ones having to live in this horrific conditions. And I refuse to go back and live with them because of what he has done and is about to do. My brothers are 2 and 4 years younger than me and had so much more freedom than I did living in that house. What should I do? And do y’all think I’m wrong for thinking this way? I just want to be happy and I feel like they (mainly my dad) is standing in the way of that.
