I second your thought of the behavior of husband; what you, kml and DnJ mentioned gave me the clue. The 'reconstruction of the house' !!
They've been expecting the construction for years even before our wedding. Now it is becoming real but they are facing the packing and moving in coming 60 days, and they have to find a place to stay even though husband is not live with them. I believe the contact between family and husband was increasing. And the next issue they have will be property dividing among the brothers...I guess.
I got nothing to do with the house matters and I'm not going to get involved.
Father in law had heart disease, he had bypass surgery last summer, he is 81 now and is getting more and more weak. He doesn't eat and takes a lot of pill but no one takes care of him(he had an affair 30 years ago and he moved out of the house for several years, my mother in law did not reveal it to me, I learned this from a very good friend of husband) Husband is pretty cold and distance compared to the moment of bomb dropped, He said his father was a person with a hard life and I'm the worst daughter in law, he showed so much emotion towards his father that time and the feelings are gone now. Non of them wants to take the old man to hospital...
Thank you Job, I will pray; there are the problems that only God could fix/solve
