Did he rejected me?

So, im 16 and i like a 18yo guy... we chat a lot, we get along pretty well. A few days ago I asked him for his number, since we always talk on Instagram. He told me that he was going to give me his number, but only if I told him my intentions. I told him that I really liked him and that I thought he was cute. So he asked me my age, I told him I was sixteen. He gave me his number and said "no flirting intentions". I asked him why, and he said in a very tender way in Spanish, that i was very young (chiquita🥺). We continued talking and then I apologized, because I didn't want to make him feel uncomfortable. He told me that he was not uncomfortable, and he kept saying very sweet things to me. He told me that talking to me was VERY nice, and that he thought I was nice. The next morning he sent me a message saying the same thing, that I was great and other things like that...
I want to add that at one point he told me "were you only talking to me to flirt? 😩" to which I did not know what to answer..

I don't know what to do about it, he is very cute, but he already told me not to flirt with him. Still he tells me such nice things... :(
Did he rejected me?
