I caught my BFF flirting with my crush!

I never thought I'd be in such an awkward situation. We were at a party when I noticed my best friend giggling and leaning into my longtime crush. The chemistry between them was undeniable, while I was left on the sidelines, confused and hurt. Should I confront my friend for breaking the unspoken code, or talk to my crush about it? It feels like a betrayal, but maybe I'm just overreacting. Would love to hear what you would do in this situation. #FriendshipDilemmas #AwkwardMoments #CrushConundrum
