He treats me like we're seeing each other but then says we're just good friends

Anonymous
I'm so confused. I really like this guy who was a casual friend before I realized I had feelings for him. He treats me like we're seeing each other, flirts with me and does things he doesn't do with his other close friends who are girls. In fact they're closer friends with him than I am and he's never as affectionate with them as he is with me. We've been flirting for about a year and recently it's become more intense. He comes up and hugs me from behind, pulls me into his arms and onto his lap, bites me playfully and so on.

He knows I wouldn't sleep with him just for the sake of having sex so I can safely say that this doesn't have anything to do with sex.

I've been out with him alone once.although it wasn't very clear if it was a date or not.

But when I got a mutual friend to ask him how he feels about me (I know that in the past he's been comfortable talking to this friend about his love life) and he said that he thinks we're just really good friends.

I'm so confused and hurt cos I thought we were actually getting somewhere.

Would appreciate any opinions on whether or not this guy is worth pursuing. And guys.do you think he's telling the truth when he says we're only good friends? I'm finding it really hard to accept it.

Also I forgot to mention that after he told my friend that he thinks we're just really good friends, he asked her if I'd said anything and she said that no I don't mention much about my love life and that she was probably just reading too much into it.
