WHY does he do that?

We went on a road trip with my mother to take her to start a trip to alaska with some family. It took about two hours to get her there. All the way, anything I commented on was ignored by NH. Anything my mother commented on was the start of a great conversation between NH and mother. I was ignored, and treated like anything I had to say was a waste of breath. Do other people notice this treatment when they're around it? Makes me feel CRAZY!! AND LESS THAN HUMAN!!! We went to some friends home for dinner after we got back and played some cards...of course I played a card WRONG and he just kept asking Why did you do that? Why did you do that? Why did you do that? Not wanting to start something around friends, I took it like a good little wifey and just sat there. He was all ogly around the friends wife. He just dottled over her....ugh! Do people see this? I feel like I'd be better off in an insane assylem sometimes. Need to talk to my therapist about this!!!
