They seem to have a knack of influencing your thoughts, at the time you may not know it is happening. Mine was a charmer & manipulator, before I met him I were focused & clear thinking, during & after the relationship my thoughts were so screwed & twisted it is like I had been turned inside out. All of the while he had a smile on his face & a calmness about him. I would suggest that you look at his whole behaviour rather than this one incident. Just after we split my ex was decent,normal & straight with me during a discussion that we needed to have. This was in total contrast to how he normally was,it may have been a calculated ploy on his part to manipulate my thoughts.
