I wonder if you're giving him mixed signals. I suspect if you feel a bit awkward with him sometimes, he may interpret this as lack of interest, and then when you're relaxed and happy your body language and facial expressions are telling him something else. He's probably a bit confused, poor guy. I only say this as I was once told by a man that I did just that.
You've been out twice and he texts you all the time. If he just saw you as a friend, I don't think he'd bother with all the texting. Is he continually texting all his other mates?
Next time you're together, why not give him the opportunity for a bit of kissing. And I don't mean jumping on him and shoving your tongue down his throat. But when you're standing or sitting close to him, just turn your face towards him, hold eye contact and smile a little... and see what happens. x
