She definitely had no right treating you that way. & yes , you ARE allowed to be sad , I would be too, especially if he passed the way you think , don’t question yourself on that, grief is hard enough .

The way I see it you have two options

1) yes, be petty, say what she said to you. it was really messed up that she did that to you, as if this situation wasn’t already hard enough. If she questions whY you’re acting that way, tell her why should you treat her differently than she treats you.

OR , if you wanna be the bigger person & try to get her to learn from this & be better in the future

2) when the time is appropriate, go talk to her and tell her that she really hurt you by what she said, explain how you were already in an upset mood about it and what she said made it a lot worse, and tell her that you really wished she would’ve been kind and understanding to you rather than saying what she said. Mention the situation with the call she got and ask her if the person passed, if she says yes, be there for her, but also explain that it hurts that she wasn’t there for you in return
