Been a while that I was actively posting here and it's the first time that I'm pushed asking a question because I can't come up with a clear decision.

Long story short: been seeing and vetting a girl for a year now, she's been really great and has/had potential being a LTR so far. But.. after a recent call I found out that she's going on a big festival at the end of June with her girlfriends (during the call she was shortly talking to one of her girlfriends about the festival and if it's gonna happen due to Corona or not). I remained silent and didn't act or mention it when I heard about it in the background. It got stuck in my head since then however since we all know what music festivals really are about for many people going there. The fact that she didn't invite me or even tell me makes me overthink the entire situation with her and I went far enough my thoughts of dropping her next time we see each other. I don't know if that would be the right call in that situation however and I'm still too heated to think clear.

Be as harsh and honest as usual and how you would react in that situation. Thanks.
