AITA For not telling someone they aren't invited to my wedding?
I (F23) am having a wedding soon and sent out save the dates last month. One person (F23) is very, very angry that A) they aren't invited, and B) I didn't tell them they weren't invited. Apparently, they found out through other mutuals that she wasn't invited based on just plain conversation about my wedding.
Well, she reaches out and says she wishes she would've heard this through me instead of through other people and said it made her feel terrible and like I don't care about her. She also said she thought we were close friends, so it hurt extra. She is now telling all of our friends how hurt she is by not getting an invite, even though I explained the situation. We aren't super close anyways. I'm just not sure what the alternative would be and I feel like it would hurt more if I singled her out and said "Hey, BTW, you're not invited to my wedding."
EDIT: I know I say "all our friends," but we are in grad school. There aren't many of us in the cohort and I'm close to only about 3. Those three I would say are mutuals that we have, as she is friends with them (but her and I are not really friends - from my perspective).
Am I seriously in the wrong here for not telling her she isn't invited?
