But isn't it nice not to know what is going on. It might take some bit of getting used to but you didn't have to hear dh go on about it all night and get all upset about it.

I say enjoy the not knowing what's going on. With any luck maybe this is his new way of dealing with it. Let's hope that if it was something serious he would be more upset about it and doing his regular call everyone who could get involved. Maybe he is taking his cue from you and is not talking about it since you don't like hearing about it.

I'm hoping for the best that this is the new DH and the way he handles his mother and her chaos. You can always hold out hope.
