Honestly, as harsh as this might sound, nip it in the bud now. He's messing around, saying he wants a relationship but he's not looking? Then why is he speaking to you so much.
This is just my opinion, obviously, but it sounds like you could do much better. It looks like one of those "I don't want to be official with you, but I don't want anyone else to be with official with you either" scenarios. I'm sure as hell that if you were to walk away now, he'd regret it in a couple of months time.
Been there. Though we talked a lot (met through work and he lives ar away), never met until 3 months ago. Wd hit it off, unexpected. Never went all the way. We talk everyday, he def likes me (says he did) and we have seen each other 2x after that first time. Never went all the way. Other than that my situation is like yours, he doesn't want to make jp his mind. Is unclear. Mentioned before we ever met that he didn't want a girlfriend.
My friends think he seems to be either insecure because of the distance or seems to think i will be just here and wait for him as he makes up his mind. Meaning that he is most def interested but thinks i will be just here forever.
