(((((((Eskielover))))))) It doesn't sound like fun at all. Sometimes you need to whack someone upside the head with a 2 by 4 to get their attention.
I hope he comes around for you without your having to go to any extremes.
In the meantime-can you find a way of laughing at his stupidity so it doesn't make you so upset? You can't change him but you can change the way you react to him.
Otherwise, you'll probably stay upset for awhile or packing your bags.
I'm sorry you're feeling so frustrated.
