Want to fuck him yet mixed feelings for him! how du think he sees me?

I have a mutual friend/acquaintance really- he is in our group of friend's events but we don't talk to each other much and never alone either.

I have fantasized about male friends before, tested the waters, went for the chase and saw how far it would get me then dropped them quickly after; this one I REALLY WANT as he seems like a challenge (unlike my other friends, who I don't even have to try I just know they like me)

He is hard to get alone or approach not sure why! and I kind of doubt he's interested yet there were a few things that demonstrated the opposite (yet i think of the logic side to)like:

* I fb'd that I left my gloves in the pub, he went to the pub and tried to retrieve them for me (although that shouldn't be hard as he lives 5-10 mins away from there)
* I was on the other table playing 'Hold em facing my back against his view (across the room)yet I turn round and see him looking my way but maybe he was looking at how many players/chips were left!
* When my boyfriend went to kiss me (lightly on the lips and a hug)he left in a huff (maybe he had a bad day!)
* On a rare occasion he spoke to me face to face he talked about what he noticed about me.

Those could just be neutral things, tho I have been known to be blind to even the biggest hints in the past so I haven't really got a clue!

But anyways, I fantasize about him, I just want to get him alone tell him that I want his cock and fuck him until I'm raw!! Because he seems hard to get and I fucking love the challenge, I find him attractive and I just want to fuck him until he cannot speak...then carry on as acquaintances.... Is this normal
