Find this so annoying! I doesn’t happen half as often now, thank goodness, as our relationship is in a much better place but sometimes we argue about what we said( ( or what we believe we said!). To give an example - DH & I have taken the same week off work & he planned to put laminate flooring upstairs ( landing, our room & DD’s room). Tonight he was insisting that he always said he was just going to do DD’s room for now but that’s absolutely not true. He said he wasn’t going to laminate the stairs as they were too tricky but he never said he was only going to do DD’s room. It’s so infuriating as he’s adamant but so am I! I’m not sure this is gaslighting but he genuinely seems to believe that he did say it rather than just think it. In the end we just let it go as actually it would be a pretty big job to do it all at once & it would be nice for us to have some days off but I’m still smarting because I know what he originally said! Wish I could record our conversations! Can anyone relate?
