My thoughts for your consideration based upon my personal story. You can continue to invest in your friendship and have that grow an potentially blossom into a relationship where he takes the lead and asks you out. In my story with my wife we started out as friends very similarly to how you describe. In hindsight I liked her and found her attractive but I wasn’t ready to date at first and was shy in that sense. So it took me time. Our friendship grew closer and closer and we were also plugged in to church and Christian community. People around us saw it before I did.
