I think the most likely of these 2 options is that your husband is lying. An exaggeration is a form of lying when it's used to harm. Clearly he knows how to harm you and push your buttons to get a reaction.

I'm not saying it couldn't be an ethics issue but I can picture a therapist trying to counter his perspective with a casual observation (I think your wife would see things differently than you do) and an abusive person would spin that to try to get a reaction so his cycle of abuse can co tinie.
