I had a similar situation recently..and the advice one of my friends gave me that was REALLY helpful was that I should say how I feel first, because my feelings were starting to get serious.
I knew that if I shared that and he did not feel the same way, it could be horrible-feeling and the whole thing could just end right then and there..
but I also know that in the past, i've kept my growing-serious feelings to myself, even while the guy was making it clear that he was just being casual, this allowed me to feel like maybe it would get to be mutual with time, and it never did.
so i took the chance and told this guy that i DO like him, and since he's the slightest bit shy too, it was good for him to hear that- for all I know, he was the one thinking he was alone with his deeper feelings. so we figured out that our feelings were for the most part pretty mutual, but i did not have to put him on the spot by saying "how do you feel about me?" because that question can be very hard to answer- especially if you do not know what the person asking it is feeling, you know?
so my advice would be what my friend said- start with saying how you feel, and see what he says to that so that he has the choice to share, knowing how you feel
i think honesty gets easier the more you practice too..it can feel so good and relieving to just share your honest feelings face to face with someone
