Is this financial abuse and can I leave safely

I’m 27F and my boyfriend is 31M. We’ve been together 3 years, living together 18 months. Lease is only in his name. I’m in school and work part time, so every rental place wants income I don’t have. He pays most of the rent. I buy groceries, my phone, and random bills when he decides it’s my turn.

I keep deleting this because I can hear him saying I’m dramatic. He checks my location and calls it joking, but if I shut it off he goes quiet and asks where I really was. He leans over my shoulder when notifications pop up. If I answer a text late, I’m hiding something. My friends are putting ideas in my head, so now I barely see anyone except one school friend, K.

The money part is what makes me feel stuck. He keeps my debit card in his wallet for emergencies. Last Tuesday around 7:40 before class, I was at the gas station near campus with my brake light on and 11 miles to empty. I had to text him for gas money like a kid. He sent $18, then wanted to know why I needed that much. Later, in front of his friends, he called me his dependent and said I’d be homeless without him. They laughed. I didn’t even know where to look.

I don’t think he would hit me, but I’m scared of leaving wrong. He knows my class schedule, work schedule, and where K lives. She said I could maybe sleep on her couch, but I’m afraid he’ll show up there.

What is the safest first move? Getting my documents? Opening a bank account he can’t see? Talking to a DV advocate before I tell him anything? Is this abuse if he keeps insisting it is just him helping me?
