My guy friend just asked me to be his valentine? How do I explain that I just want to be friends?

Okay so I got something in the mail from him which was very sweet of him. He sent my a box of chocolate and a note asking me to be his Valentines.
I don’t know if it’s a Valentine as a friend or romantically.
I texted him, “Thank you for the gift but you asked me to be your Valentine. As in a friend or like more than a friend.

Then he texted, “More than a friend. I want you to be my girl and you’re the only girl I’ll ever love.”

Thats very sweet but the I just don’t see him the same way and I’ve explained that I just see him as a friend. I told him that like years ago and he stopped asking. We have known each other since we were 8 and now 29. Almost 30.
We’re both autistic and I don’t think he gets the hint. Even though I bluntly said we are just friends.

I texted him “I prefer the friend Valentine….”

he didn’t text back
