Accidentally disclosed that I (23F) live alone to a guy

I rented a vacuum from this guy, and I think he found me cute and I was interested too when he came to deliver the vacuum to my place. After I finished using it, our texts continued to be more and more casual, and he asked questions like ‘who do you live with? Your home seemed quiet,’ I replied with ‘oh I live alone but my parents come over very often.’

I thought it would be okay to just mention that since he already has my details anyway (I had to fill up a form for the rental, and he also happens to be the owner of the company). But now I’m second guessing my safety choices. He asked me again, what’s my rent like, and how many rooms there are at my place… I answered the rent part but I didn’t answer the question about how many rooms.
