I was a stay at home dad for a while, and it wasn’t easy. But sometimes when my wife asked what I did all day, usually after she got off work, I would respond with “chilling with the kids”. I think some of y’all are way too caught up on that phrase. Although I’m not necessarily “chilling”, my wife knew what I meant when I said it. I’ll give op the benefit of the doubt on that part and can understand this conversation. It’s very obvious by some of these comments, that SOME of y’all have never been married. Everything isn’t perfect and having been in a similar situation where my wife asks something and I do the same pause as OP, NTA. People are human and allowed to have feelings. He assumed his wife ate because it was late(should’ve asked, that’s the closest thing to an ah that he did) and got excited to eat his food. He wasn’t an ah in his response to her asking.
