Ok so i'm at a bit of a loss here, had a great first date with someone. We had shared interests, clearly found each other attractive, danced together and had great sex. She then stayed over the whole next day and we watched films together. it felt nice and i expected things to go somewhere (however casual). The next date she pretty much ignored me and was clearly into another guy at the gig we had planned to go to. I just feel so stupid, was that first date just too much or relationship feeling? We've barely spoken since yet she's watching my social media. it's also quite apparent she has a thing for anyone in a band, it feels like a waste of time to even put yourself out there if you are just going to go off with any musician you bump into. A part of me wants to communicate that i was disappointed and actually disrespected but figured what's the point. It feels like whiplash and it's got me feeling so down.

What would you do in this situation?
