I wonder if this upcoming move had been a point of contention lately. Getting closer to the time of the move, and no luck with finding housing. Which raises questions.
If she had been trying to get campus housing and he was not enrolled, thus no housing... then what house were they moving into, IF there was one?
And why leave work early?
It'd be a pretty big shock to find out that you are moving within weeks, probably had given notice on the apartment, you are pregnant, now there is no school, ho housimng, no job, no scholarship, or grant. She's thinking, "I've got to confront him and find out what is going on." Now she finds out that his previous college graduation was faked. She's been married to this jerk for 5 years and now she wants to kmnow what else he's been lying about...
And he didn't know she would be calling to arrange housing??? Doesn't that sound a little off? I think he probably dismembered her.
