He calls me a friend?

So he flirts with me (even sexually or romantic), talks to me almost everyday, normally the he is first to text. Speaks on call for long hours and goes in to deep conversations. Wants to meet up in real life, hugs me. He talks about how he cherishes my time or me. But if I flirt with him he says I like how open you are and that we are comfortable as friends.

He has ADHD and he has never dated, I have autism.

I feel like I need to back up but then he hints that maybe he likes me back but then says "friend" .
