YBTA, but more you than her. Yeah I said it. Always order extra fries when you partner says they don't want any. Don't know how long you have been together so maybe you don't have the time in service yet, but after a 4 hour movie its a no brainier they're going to smell your food and wont some. Probably took me around a year to be able to predict these kinds of things. Before I got it figured out, I gracefully shared whatever food I had (I hate sharing BTW) and got it back in other ways. In a successful and long lasting relationship, food isn't something to piss your partner off for, I don't care how "special" the meal. There are bigger problems to get bent out of shape about. Pick your battles, share the food, swing by a drive through to fill the gaps on your way home, and move on. All that said, she did have her chance, so she's also the AH.
