Dear Sophia:

I would call one of the three, at the least, the one who responded most positively to your reaching out effort and ask her about the meet up posted on social media, ask why she didn’t invite you. I wouldn’t go into a long story with her, simply ask. And not in a hostile or emotional tone, but a neutral, natural tone. Ask simply for information, because you are curious.

Maybe the meet up was a spontaneous kind, not one that was planned? I don’t know. But I don’t see any downside to asking. I don’t think there is any loss if you ask. It may be stressful for you to ask but also a good exercise…?
