Is it possible that he completely lost the capacity to "read" other people's feelings? Like almost insensitive to social cues? Just because I do not yell, or cry, or whatever does not mean I am ok with him. I know they are selfish, but he is beyond that. It might be denial, it might be not taking me seriously, it might be that he thinks I will not be able to leave because my resources are more than limited (or so he thinks).
Good thing is that we are being civil to each other. I better create my safety net fast, because something stinks here.
