My Boyfriend Is a Binge Eater????It's a Disorder from Childhood?

My refrigerator is ALWAYS empty because of him. Ordered a Large Pizza and had 2 slices. Along with ordering 10 buffalo Wings. I stepped out for an errand 15 minutes he had Eaten the whole box and all the wings too!!! I told him this is rude (he has done this before) He DEVOURS everything I cook. I brought a gallon of juice one afternoon I didn't have a sip. He drank the whole jug. He leaves his clothes on the bathroom floor and I have to get on him about cleaning up after himself (leave his food on the counter) I cooked 7 Pork Chops (big ones) He at 6. He asked me to fry 20 wings for him and I said hell NO. There is nothing ever in our refrigerator because he ALLWAYS has the Munchies. If you see his body he is built like a Ken Doll (Barbie's companion) He said as a child his mom was on drugs so I guess he REALLY cherishes a meal being as though sometimes he didn't eat.
