When a man considers you his special friend, what is he saying exactly??

A friend zone with extra emphasis, sounds like

Ask him.

Either a friend he won't screw around with, or precisely the opposite.

He may just want you as a best friend of sorts, like to travel with but not a sexual relationship. I've only had one like that via a penpal relationship, she was blind and I was thinking of bringing her to the US on a trip or traveling with her in Europe. But things eventually got weird and I realized I made the mistake of letting her know alot more about me than I knew about her. I don't like a lopsided friendship like that.

You wear a helmet and lick the glass on the short bus?

Probably flirting or friendzoning you

only once in life i got that opportunity , he told me " be my special so I can clean my tongue regularly there "

That he wants more than what you are willing to offer

Is he a cowboy?
