Why Did You Introduce Me To Your Parents?

I want to share what a strange thing happened to me. I am a 22-year-old girl, I have been dating a boy for 4 months, our relationship is purely friendly, in the sense that we meet, help each other, have sex, but we are not together. From the beginning, I didn't want to bond with him and he with me. We talked about this very often and we had both ended serious relationships. It became clear that we will be friends with extras, no feelings, just sex. See you 1-2 times a week. Everything was OK until I became attached to him. I can't say I'm in love, but I'm definitely used to it. A few days ago it happened so that he introduced me to his parents, introduced me simply by name, did not say my girlfriend or a friend, just "this is ...." and so on, which was a shock to me because it all happened so by accident unforeseen and fast and I was very worried and everything was so strange to me. Then he told me that he was considering how to introduce us. At the moment I don't know what to think of him, of us - if there are any of us. Treat me as before, in a friendly way. We haven't heard from each other for 2 days, I don't know what our relationship is like at the moment - are we together or not, but I'm afraid to ask him. I don't call him so as not to annoy him. Please give me some advice. How do you think things look from the side, because I can't judge for myself. Thank you in advance.
