This just seems like flat-out abuse. Gaslighting, when it was done to me, was much more subtle. When confronting my ex about something he'd said/done in the past that was different from what was happening in the moment, he'd say, "You must be confusing me with someone else again." Or, "I never said that." Even when I remembered the context and the situation, he denied it and I was left wondering if I could trust my memory anymore.
Granted, he had the memory of a gnat, so it may not ALL have been intentional, but it was always a very subtle, insidious technique that made me doubt myself. Over time, it eats away at your confidence and you truly do doubt if you're remembering things correctly.
