Welcome from Pine Grove, CA.
Your son sounds very normal. My son at that age spent most of his time laying on the couch eating burritos. He outgrew it, lost weight and got in shape when he went away to college.
Tell your husband he is lucky. I'm like you with piles everywhere except that my quilting area is now the living room. At least he doesn't have to look at your "mess" all the time.
(this is what happens when kids grow up, I guess.......)
