The issue of Boredom

I see this mentioned frequently in NPD literature and on this site: The N gets bored easily. I find this to be a contradiction of sorts. I thought my N was boring because everything had to be so structured to meet his compulsive needs. His bedtime routine, his breakfast routine, his work routine, his exercise routine, watching the same movies and movie clips over and over, his bible study routine......He bored me! I had friends and other things in my life. He had his routine and exercise buddies who he tried to corral into his training routines to make himself better.

He tried to vary things initially in that we went out to dinner and had a few fun outings, but after that, it was rote routine. I even mentioned here a few weeks ago how I saw him walking with the new OW through his old neighborhood pointing out his old house exactly like he did with me. BORING

I am not sure I want to even credit these pathetic people with the ability to be bored. Desperate to grasp something they don't have and can't hold on to perhaps, but not sure it is boredom. I assume it is because they do lose interest in their surroundings but I think it is a deeper psychological battle rather than basic boredom. Their need for change is a survival technique because they cannot live with themselves for very long.
