Is it normal if my friend acts passive-aggressive when i can't hang out with her?
I've been best friends with this girl for 3 years now. I am the president of a council, I work regular 7am to 1pm shifts and I have younger siblings who I have to take care of once I head back home, while my best friend is an only child, and isn't working at the moment. I've always made enough time to call her throughout this entire pandemic but now that September is approaching, I must help my siblings prepare and help them before they head back to school. I don't have enough time to call her since I am very exhausted at the end of the day. She's become very passive-aggressive towards me and tells me that I'm always busy (I actually am). I told her about my situation and the responsibilities I have, and all she does is mock me about it.
TL;DR : I have a very full schedule, and I am very exhausted at the end of every day while my friend has an empty schedule. My friend gets upset that I won't make time for her even after I explained the duties I have.
Is this normal behaviour?
