Neph....I'm tempted to think that perhaps he really is sleeping on their floor. She may be a 'rescuer' and has taken him in like a stray cat. Unless her bf is twice as codependent as she or your h is, I doubt that he would be ignorant of a PA in his house. Unless of course, he isn't really her bf at all.
REgardless, it is still an EA that your h has going on and if it's support he's getting then in his eyes he hasn't really done anything wrong. However, I feel that a wife has the right to know more about her h than anyone else and if he is confiding in other people (that aren't professionals and aren't okay with you) then that is breaking a boundary.
In any case....I thought I'd just point out that from your h's point of view, he may not think that what he is doing is wrong and may think you are p1ssed with him for reasons that you are unaware of.
Don't try to mind read. Deal with behaviour, not motives because you don't know what they are.
