AITA for telling my BIL to pay me for the groceries he ate while house sitting for me?

I (28F) own a cat and recently went on a week and a half vacation with my fiancé (29M). My brother (25M) and his wife (26F) housesat for us while we were away. Before leaving, I told my brother and his wife that there were some groceries in the fridge they could eat while they were there, but to please replace whatever they ate. <br><br>When we got back, my brother texted me his Venmo address so I could pay him for the services he performed while housesitting (watering my plants, collecting the mail, etc.) We agreed on $200, which I thought was a bit high but whatever. I sent him the $200, and he texted me back, saying, “Thanks! Also, we replaced all the food we ate. There was a lot of stuff in there.” I thanked him and thought nothing of it until I got home and saw that he had not replaced everything. <br><br>There was a half-drunk bottle of OJ in the fridge, whereas I had left a full one. A full unopened container of almond milk I had left was now half empty. An open container of pineapple yogurt that was full before was now almost empty. There were two unopened containers of almond milk and two opened ones (which I had drunk myself), and BIL and his wife had drunk both of the unopened ones. I had also left a bottle of my favorite sparkling juice, and it was now empty. <br><br>These are all small things, but since they were supposed to replace what they ate, I figured I would text my BIL and let him know I was disappointed that they did not do that. He said they replaced most of it and that “we weren’t made of money.” <br><br>I told him that they didn’t need to drink all the food I had in the fridge. If they wanted to replace it but couldn’t afford to, they could have told me and arranged not to drink those items. He said, “You want us to pay you for a half empty container of OJ?” And I said yes, since they didn’t replace it and drank it anyway. <br><br>He said, “You want me to Venmo you $2?” But he never actually did it, and that was the last time we communicated about this. His wife then posted on Instagram a photo of the almond milk with the comment, “Best almond milk I’ve ever had,” and she tagged me in the photo. <br><br>I thought that was passive-aggressive and told her so. She said, “You’re telling ME I’m being passive-aggressive? You literally want us to Venmo you $5.” My BIL then got involved and said, “Yeah, and she’s telling ME I’m the asshole on Reddit.” I told them both I thought they were being petulant and that it was not about the price of the food but that they didn’t replace it after I asked them to. <br><br>My BIL then wrote me a long message about how childish I’m being and that I’m not getting the $5 and how I’m spoiled and entitled because I’m expecting to be paid for the groceries they ate but didn’t replace. He said I was overreacting and that I’m being petulant by telling them both that they’re being petulant. He also said that I need therapy to work on my mental state. <br><br>AITA for wanting BIL to pay me for the groceries he ate?
