AITA for not telling my friend the homework we had

Hi, so like my friend is really mad at me because I forgot to tell her about an assignment we had for tomorrow, it was like 8pm and she asked about it because in another group chat someone asked what assignments we had for tomorrow and I mentioned that one. She missed school on Monday the day that assignment got send so she relied on me to tell her what homework the teachers sent us, I did my best to tell her and remember all the assignments we got that day (which were a lot) but this one (and another one but someone else made me remember and we got it done in time) really slipped past me. To be fair I once skipped school for 1 week because I was sick and she did tell me all the assignments we had but it was like the first week of school so we didn't have a lot of assignments but she brought that point up which seems fair. She's a very responsible person and its the 2nd highest gpa in our year so I know she must be frustrated right now but I don't think she has the right to be demeaning towards me and question what kind of person I am (for forgetting 1 assignment) (we are jus texting rn for context but I know she will give me shit tomorrow and make me feel bad, I already apologized as it was an honest mistake and I just remembered it myself so I'm doing it right now too because I genuinely forgot)
