I get "called into work" when I can't take my wife anymore.

I am in a field where I am on call 24/7. I get "called in" to work a lot on the weekends. I really do go in, I usually just do busy work. But no one calls. It is just quiet and I don't have to deal with her for a few hours. I don't think she cares as she is constantly at her moms or out shopping with her. Before someone says "she's cheating!" they ride together and come back with shopping bags. Her parents live on our street so I can see her car over there from my driveway.
