AITA for saying I’ve seen specific movies with my husband?

I (27F) had a conversation with my husband (30M) of 5 years and sister (16F) today and a niche movie came up. My sister asked if my husband had seen it. I said he has since I remember watching it together with him a couple years ago. He then vehemently denied ever seeing it and disengaged from the conversation. Ever since that he’s been ignoring me and refused to eat the dinner I made.

It has happened several times before where I know for a fact we saw a movie together but he argues it never happened and that I must’ve seen it with someone else and am now gaslighting him.

AITA for saying I’ve seen movies with him that he doesn’t remember seeing?
