Is there a nice way to tell someone you don't want to talk to them anymore because they no longer offer you anything?

It's easy to be direct in saying this kind of stuff, but holy geez...who'd want to be on the receiving end of it? 

Cute Butt Boy text messaged me tonight, and when I replied I mentioned that I wanted to talk to him about his last visit. He said he'd call me, and we just got off the phone. I'm just frustrated. I think I wanted the easy way out. I told him his visit shouldn't have happened, and I suggested we just not talking anymore.

Because what is the point? Am I too cold to think this? We were "buddies," and that was all. We never went out and did stuff, so I didn't consider us to have dated, and I didn't even consider him a friend.  I don't hate him or anything. We have a good time when we're together. Come to think of it, I usually turned down or missed opportunities when he did ask to do stuff.

I think what I wanted to hear was "yeah, there's no point anymore," but he said he had fun talking with me last night.

I hate having talks about next steps. I reminded him that he wanted to discuss things before, but that he did not follow through. He said "oooh, that's right." I guess he is content knowing me as an acquaintance, but I don't know if that's possible for me.

It's rare for a guy and girl to be just friends, but I don't think I could be friends with him, considering I would have wanted to date him if he wanted the same thing. And even though I know he's not suitable for me long-term, I guess I am somewhat wistful. It's this physical attraction and his fun factor.

And I have not brought up UnPorsche to him again. I would rather just leave that out. I don't want him to think less of me. I feel like I am not handling this situation very well.
