Two things: 1) The point of dating is to get to know people and see if they are a good match for you...and now you know that church guy just isn't. That is neither good nor bad--just a fact. You two don't fit well together. Period.
I'm sure he is a fine fellow, kind and caring and courteous and all that...he just isn't FOR YOU.
2) Regarding what you called his aversion to food, I would like to possibly suggest that you take a potential new perspective on that. There are many people in the world, who, for a variety of reasons, have a specific or limited diet (meaning "what they can eat"). Some folks have allergies or can't eat dairy without distress. Some have an illness like Crohn's and have to be gluten free. Some have some medical procedure and just don't digest meats or fats well. BUT they can still be an absolute foodie!! Just maybe not at restaurants.
Restaurants oils to fry their fried foods are often inexpensive, vegetable oils which can be tough on digestion. Restaurants love to serve steaks as a special meal, but steaks are red meat and can be hard to digest. Restaurants often add cheese to everything or bread everything. Now I'm not saying restaurants are "bad" but if someone had Crohn's for example...poof all breaded food is off the plate, as is bread, buns, rolls, cakes, etc.
Alternatively, at home, if someone is a foodie but loves to cook, they might fry foods but use olive oil. They might make a nice thick, lean pork chop with a fancy chutney. They might have dairy-free recipes to make amazing side dishes. They might have recipes for gluten-free dinner rolls and cookies. Thus, their foodie nature is displayed in their love for food that they can create AND EAT without digestive distress. And if someone had a serious allergy, or illness or something, they might want to allow others to feel the joy of going to a restaurant but also know that what they can order without getting sick the next day.
Sooooo...long story short, don't assume people aren't foodies just because they don't like restaurants. Keep your mind open to the possibility there may be a creative chef genius who works around their own dietary needs to eat well and not get sick.
