Ok so i had a really pleasant date with a girl, we really clicked and had a lot of shared interests. We were intimate together and she stayed over essentially the whole next day. All great so far, I was planning our second date to see some music. i recommended a event i wanted to go to and she mentioned that she would be down but some friends she's knew/had met from a previous gig would join. Felt a potentially yellow flag for date logistics but went along with it. So i got the gig a bit later than her, i noticed straight away she was hanging with two attractive guys. Took a little while to say hi and it felt a bit awkward, her focus was more on one of the guys and her body language was very much showing she was interested/attracted to him. Kept my cool but felt a little weird considering the whole idea was supposed to be us hanging out, still had a nice time and we hung out a bit but we all got quite drunk and went to leave. As we were leaving she disappeared with the guy and i was left with her friend. We then kinda clicked and ended up at my place, i think i was kinda just thinking why not especially after kinda getting pushed aside for someone else.

So we hooked up, and she then spent most of the next day with me. So any advice on this situation? Should i pursue the first girl still, pursue her friend, am i a bad person for doing this? I've had a real lull in dating and i'm genuinely trying to date with intention but things like this aren't helping. It was a little awkward as her friend kinda found the situation funny which i also laughed about, they will see each other soon and "gossip". I've got no idea what to do or if either of them will want to see me again. I'm happy to hangout with both of them at this point as i liked both but the whole getting sort of ditched makes me a bit confused about the first girl.
