That's exactly what I said the other day. I told him that I feel like I am so used to the mean comments that now I automatically get defensive even when it's not necessary. His facial expressions and tone do not change. Ever. That is not an exaggeration. I have had several friends tell me that he was 'inanimate' or couldn't tell if he was joking or not. So things come across as mean no matter how he says it. I literally have to ask him how he means certain comments. And now I feel like I am just so used to that blank expression that everything sounds mean.
