AITA for reading my girlfriend's mind?
So my (19F) girlfriend (21F) is also my classmate at university. Both of us go to a magic school, and she's an upperclassman and a star student. I have the power to bring back the dead, and last semester after we tried a magical ritual that went wrong, she ended up dying. I managed to revive her in a few seconds, but it was really scary and traumatic for both of us. Also, for context, her parents are separated, and she lives with her dad, but I think she likes her mom better.
After a pretty eventful last year, right before winter break, I learned her mom is actually an evil lich, and was hiding it from all of us. I tried to tell her, and we had an argument about it because she didn't want to believe me. Finally, she told me she found out it was true, and her mom was inviting her to stay with her during winter break and undergo a magic ritual to become a lich. That was super scary for me because liches are soulless and, as far as I know, evil! But she didn't want to believe her mom could be evil, and after what happened last semester, she was interested in doing it. Both of us were pretty messed up by what happened— I didn't want to lose her again, and she didn't want to be put at risk of dying again. I begged her not to become a lich, but she told me it wasn't up to me and we went on winter break on a pretty sour note.
After we returned to campus after break, she seemed really awkward and had purchased a very expensive gift for me and wasn't willing to tell me anything about how her winter break went. I was really worried and scared, and didn't know if she had become a lich or not, and so against my better judgment, I secretly cast a spell to read her mind. It was just for a few seconds, and I could tell that she was really worried and upset about telling me something. I told her immediately afterward and apologized, and she left and now she isn't talking to me. I know it wasn't the best move, but I just wanted to know if she had lost her soul or not. AITA?
