Kelly Jo, I remember how stressful it was for me when H was in the house and his focus was elsewhere (OW). When they are still home it makes detachment doubly difficult.
Have you tried leaving the room a few minutes after he enters - to do something which you enjoy doing? (I know, it's hard to think of anything enjoyable now.) I don't know if you still eat together but, you could try changing your mealtimes in order to go to a GAL activity outside the house.
