I really think MOST of the glutening I get is because hubby still eats gluten in our household and even though he thinks he's being cautious, I still feel like he's getting it on the fridge door or microwave or somewhere and I come along and pick it up. Maybe one day he'll stop.
You could also be glutened by his kisses if he doesn't brush his teeth first. It can be hard to live with gluten eaters but it can be done safely. If you can get him to use just one space on a counter to make a sandwich or other gluten item and perhaps get him to wash his hands after he eats that may help.
