For context, my family is from a Middle Eastern country, although I was born in the UK and partially grew up in the US. So there's that clash of Middle Eastern and Anglo-American cultures, especially when it comes to boundaries, family dynamics, etc.

I (34M) flew to the UK today to attend my mother's (71, almost 72 F) British citizenship ceremony and see her in general. Earlier today, my mom and I were hungry, and she suggested I go out to pick up something from the market nearby.

I go out to get some arancini rice balls from a street food vendor and bring them back. I like it, she didn't really so much.

While she almost finished her meal, I got full and wanted to save the rest for a snack or something later. She said she wanted to throw all of the food away. I insisted I wanted to at least keep my portion, which she agreed, and I wrapped my food in the paper wrap assuming it'd go into the fridge.

After some time, we're about to go to bed, and I asked if she put food in the fridge. She said she threw it away. I asked if she was joking, she wasn't, and showed me the (small) rubbish bag she put it in.

I asked why she did that when I specifically said I wanted to keep my portion. She said it was because it was "disgusting". I got annoyed and said that it felt like she was undermining and not respecting my wishes. She insisted that it was disgusting and we'd go out for food tomorrow anyway, so it didn't matter. This got me upset and I told her how it feels like she doesn't respect me in general, how it's no wonder I have low self-esteem due to her undermining me and making me think what I do isn't worth it (many things I've come to realize due to therapy).

She then said that she compares how my cousins treat their mom vs how I treat her (saying that I treat her bad...despite her criticizing how crazy and toxic everyone on that side of the family is not one hour earlier). She started crying and the left the room for a bit.

She came back, and to try to have a healthy conversation about the topic, I asked her why does she think I'm upset in the first place....to which she's now giving me the silent treatment...

Am I the asshole, or am I going crazy??
