I hope this makes sense. I had a big fight with my partner because I found out that he had been lying to me about something. This had been a bit of a mess as I had suspected something but he had always denied it and he did have me convinced of his version for a while. We were both angry and loud, but at some stage he just got a "blank" look at got entirely calm and quiet. At first this made me even more annoyed but then I felt really unnerved and just stopped talking too.
Does anyone else's partner "gloss over" like this, is this a thing? Or a defense mechanism? He was definitely caught lying.
