Advice please💔

My boyfriend and I have been together for almost a year which is the longest I’ve ever been in a relationship. And we’ve experienced everything together. The problem is he’s toxic. He’s beyond controlling. He has all my passwords he makes me keep my location on at all times. I can’t text any guy friends or walk with any of my friends in school because I have to walk with him. He even made me stop talking to my best friend because he doesn’t like her. If I don’t do what he says he threatens to break up with me. He’s also insanely jealous. Everyday he asks me if a boy said something to me. He constantly disrespects me “dumb fuck, bitch, you’re pathetic” he’s insecure he’s antisocial. I feel like he’s trying to isolate me to the point where I don’t talk to no one except him. Overall I feel like he’s dragging me down. But I love him and I can’t see myself without him. I don’t know what to do
