I am sorry you having your nose rubbed in the perverbial. I do not know why they cant wait until they have left before they go and do exactly what they want to do, irresective of anyone elses feelings.
There is a fine line between being friendly and living as room/house mates and being a doormat.
Knowing what I know now, I would have shown my wife the door when this first started, it would have saved a lot of psychological hurt.
