Of all possible psych issues for him, GAD is only one possibility. This poor soul had to deal with so much in his very young life as well as later on. Who can even begin to imagine such trauma?
As far as I know, they knew each other only 3 months. Read something that said she was merely staying that night, too tired to drive home. My problem is I am unable to reconstruct a scenario, refusing to buy into Nel's reconstruction. He may well have thought he heard an intruder in the bathroom where a window was open. In his fear, awoken out of sleep, he forgot about R. Grabbed his gun and leaped out of bed. I never detected anything that his possible abusiveness (was he abusive?) went as far as it did. He needs that dream team defense because I do not believe he intentionally killed her. The ultimate culprit here may be the gun and the ready availability of guns. We have a terrible problem with them here.
