I’m vegetarian and my mom hates it

TLDR: Mom told me she was “glad I moved out” and that my sis and I would “ruin things” for her.

Today I visited my mom and she cooked dinner for the two of us. When I saw some meat in the plate, I asked her if she wanted mine. She said “sure” and I gave her the meat. She seemed thrown off and asked if I was actually serious with being vegetarian (I already ate vegetarian on Christmas). I said I was, but I’d eat the soup anyway this time, because she didn’t seem to have known yet. I still thanked her and said the food tasted great.

After a suspiciously long time of silence, I asked if she was disappointed. She answered she’s just happy I moved out, so she doesn’t have to be considerate of me being vegetarian. Then she added that my vegan sister and I would ruin things by making it difficult and started crying.

Tbh, since my sis has been vegan for quite a while now, I didn’t think it was a problem for anyone. Boy was I wrong. Her reaction was a slap in the face to me.
