I’m trapped in a relationship?!?!

So last night, i was on a phone call with the guy I’ve been talking to for 2 months tommorow. Mid conversation he’s like “happy one month anniversary baby”. And he was serious about it, I thought and was hoping it was a joke. He asked me out one month after talking to him and I said NO because I never met him and don’t know what he looks like and he lives on the other side of the country. He says the next day after he asked me out and I said NO he asked me out again when I was asleep and I said yes😂☠️😭 so he thinks we’re in a relationship for the last month even though he knows I was practically asleep and when I’m asleep I don’t know what’s going on. Yesterday he was accusing me of forgetting our anniversary 😂😂 and he got mad at me and started acting like he was upset.

What should I do? I told him many times that we’re not in a relationship yesterday and many other times and he just won’t listen. I’m not ready for a relationship and I don’t know what he looks like, I just talk to him on the phone. I can’t be a relationship with someone I don’t know. 😂😂😂 he’s very manipulative, controlling and just so rude to me. If I leave him he will spread rumours and find a way to guilt me.
