You could try talking to him. This is always a difficult situations, jumping the latter and going from friends to and "item", or whatever you'd like to call it.
If you believe he likes you and you two obviously relate, then I think you should confess your feelings towards him. Ask him how he thinks you should go about this.
I think you know the risks you're taking but chances are since this seems to be such a strong relationship already you two will last for a while. Once you split up, if you do, there will always be something there and it's going to be hard to face eachother most likely until you learn to except it.
You'll never really know unless you take that risk. Life's all about risk taking, if he truely is your friend then you'll remain friends no matter the out come and chances are he's attracted to you and if he doesn't want a relationship he won't reject you necessarly but rather, come to a logical agreement, I suppose you could call it.
Edit: I apologize if this doesn't make much sense. I'm very deprived of sleep and I'm rambling on, trying to help people but I don't really think it's working.
There's enough intelligent people on here for you to get one good response, so I'm not terribly worried.
