Am I crazy for getting mad at the tone of my bfs voice?

Tonight I cooked dinner and fed the baby. While I was doing the dishes and did an overall wipe down and sweep of the kitchen he went and gave the baby a bath. I also did a load of laundry between dinner and stuff. So I asked him if he'd put the baby to sleep and he says "I will". With a tone that sounded like I don't want to but I will. 😒

As if I were asking him sooo much. Mind you he doesn't work and I'm pulling a friggin double tomorrow, so it's gonna be at least 10 hours and guess whose gonna get up tonight of the baby doesn't sleep through the night? 🙋🏻🙋🏻🙋🏻

I'm not crazy right? He should pleasantly say "Sure babe! Draw you a hot bath and enjoy a glass of wine, then get some rest. I got this." Right?! 😠
