Am I the Asshole for Telling My Partner He Would Be a Bad Parent for Going on Holiday?

Pregnant 26-year-old told her partner he would be a bad parent for going on holiday. He wanted to go in about two weeks when she was 38 weeks pregnant. She asked him how he would feel if I handed the baby over to him after birth and went on holiday for two weeks. His response was simply crack off, then the conversation died. Am I the asshole? No. Mm-mm. That's some audacity. This is our kid, but half yours, your kid. You're going to leave on a two week holiday when I'm supposed to give birth? And you're going to do it right before my due date? It's so wild
