AITA for saying I’m not my boyfriend’s “girl”?

I’m 18 and my boyfriend is also 18. He says I’m his girl and that he’s my man. That’s fair enough I guess, but I’ve never liked being called “my/your man/woman/girl” or other terms like that. I asked my boyfriend to stop calling me his girl.<br><br>He got pretty mad and was like “you’re my girl. You’re the only girl I care about.”<br><br>I realised he didn’t care that I specifically don’t like being called girl, so I said “well, I’m not your girl then.” I just said that to make a point, I wasn’t trying to break up with him or anything. <br><br>He said I was breaking up with him and when I explained what I meant by my statement he got mad and called me a massive bitch.
