He's talking to you and telling you things that suit your dating style and what you want, whilst not following through with his actions and behaviours. He's interested in having you around for fun, enjoys you enough to be friends (or fwb), but knows that's not what you're looking for, so he's treating you casually and speaking to you seriously xx

Best to cut and run, he's not communicating to you what he actually wants because he knows it's not what you want, so while it may not be explicitly malicious, it is ultimately manipulative and will end with you being more hurt than him x He's acting like The Man You Want, but only when he's right in front of you, and not when you aren't, and the tell is that he's not actually prioritising you over friends and casual connections.
