That dude is an asshole, but it is not gaslighting. people try to apply gaslighting to everytype of conflict now. Gaslighting would be them saying you formerly told them you lived in Paranoiaville and now you are denying it. it is when somebody actively tries to twist your memory, not just contradict you , or be sarcastic or condescending.
Gaslighting is the act of trying to convince someone that they are crazy. In its simplest form telling someone who is not crazy that they are crazy is gaslighting.
