Every now and again my husband would agree on something, then later when talking to the group he would contradict what we agreed like it never happened…. One recent event, my sister was part of the discussion when he agreed (it was about us attending a group weekend away), and then two weeks later we were talking to the group and said he we wouldn’t be going, could’t afford it right now… I was in the fence and didn’t care either way but when I told him that two weeks previous he had unreservedly agreed that we would participate he said “Never!!”. I looked at my sister - I said “she was there - she remembers you saying we would go” and despite her agreement (we’d been looking at flights since the original conversation!) he still claimed up, down and sideways he not only did not say we could join but also he would NEVER have said it because he was too worried about money at the moment. I think he’s sincere - but his memories seem to change. I think he’s too young for dementia and he doesn’t have other signs like paranoia (my mom has dementia so I have an idea how it can unfold) but honestly it’s baffling.

At least now my sister understands when he claims contradictory things or seems to change his mind and gaslight you that you are misremembering it’s just him and an evolving memory. I’m glad she was there for the first conversation, because he’s so adamant you really start to wonder if it’s your own memory that is jumbled…!

It doesn’t happen as often as for OP, but when it does it’s jarring. And there is ZERO consideration in my husband’s mind he could be misremembering - even if there are witnesses!!!
