AITA for also eating for two?

So my wife (25F) is 9 months pregnant with child. I (35M) am with burrito and about to do the same. So tell me if what I did was wrong:

My wife had made some of her world famous 5 layered peanut butter banana bean and bacon burritos and made a little note that these were for her to eat tomorrow. Well, when we got married, it was my understanding that as long as the food she makes is in my house, anything goes. She started to get angry at me when she asked where the burritos were. I can’t help being a man and hungry. I only had one bite… one huge big back bite that looks like the aftermath of Jaws, but a bite nonetheless. After she asked me the question, I said that I was also eating for two and suggested maybe she should starting making two for the baby and me. I’m only trying to help her grow my child.

Now she’s pissed at me and talking to my mom about staying over at her place for a couple of days. She is also considering not letting me see my child that I’m working for two on. My friend is also calling me selfish. I can’t help being a decent normal guy who happens to be big boned and always eating for two. AITA?
