He said, "I'm not looking for a relationship..." That's pretty clear that he is not into dating with a future relationship in mind. He wants some whore action.
It's pretty clear to me that it's more likely he's looking for friendship.
It's also within the realm of possibility that you sent out crazy lady signals early on, and although he'd like to be kind and enjoy your company on a walk, he doesn't want to give you the wrong expectations.
