I have to agree. I'll be the first to admit that I was suspicious of him in the beginning. I didn't think he acted in a way I thought he "should" and his body language seemed at odds with his situation. Turns out I'm pretty cr@p at reading people. I think he's just a guy of a certain age, brought up in the country, in a time when men didn't show emotions. You just got on with things and were strong for those around you, which he appears to be doing.
Personally, I think it's time he allowed himself to grieve a bit more than it appears he is. Time to release all that tension, and emotions. He keeps saying he's staying strong for his kids, but I think they also need to see him express appropriate emotions. Of course, who knows what happens behind closed doors, but it appears he's kept it together long enough for the kids, it's time to deal with the emotions in a healthy way. I wish him well and hope that she is found and can be laid to rest. That will have to go some way towards healing.
