Controlling and manipulative boyfriend? I can’t leave. And he wants to put a baby in me next year😭😭HELP

So I’m 17 and the guy I’m talking to claims he likes me and is already starting to fall in love after just over a month. We’ve never met, he lives on the other side of the country. I don’t know what he looks like, I’ve only talked to him over the phone for the last month(almost everyday for hours upon hours). The problem is I don’t have feelings for him-or at least not as strong as the feelings he has for me. I just don’t understand how he could feelings for me already when he doesn’t even know me to the full extent, especially how claims to be falling in love. He’s seen me on Snapchat and has only heard my voice on the phone. (He refuses to send photos so I have no idea what he looks like for the past month). I don’t like him. He seems emotionally abusive, manipulative, and controlling. For example, if I jokingly say something he doesn’t like as a simple joke he’ll hang up the phone on me. Then I have to call him. But if I was to do the same he do the same he never calls me back. Last time he told me “fuck off” so I told him to also “fuck off” so he hang up and made me call him back. He says it’s a tactic he uses to teach girls to respect him and show who’s boss. I want to leave him and focus on myself for the year but I’m scared because he’s 6’8’’. I’m also not ready for a relationship at this point in time. I would like to focus on myself this year and becoming the person I would like to be but this has me tied down as I’m not allowed to talk to other guys. I don’t know HOW to leave. Please help.

He doesn’t go to college and doesn’t have a job. I plan to attend college and become a doctor which will take 7 years at least but he wants to have a baby next year. He says will start trying to conceive when I’m 19 which is at the end of next year. Which ruins my plans to go to college, travel, and have fun. Since he’s controlling he’ll find a way back into my life and to have a child ☠️☠️☠️ sounds ridiculous I know.
