So I went to this electronic music festival with 3 other guy friends this past weekend. I had a blast on Friday, just getting down to the music and feeding off the energy of my friends. On Saturday, the same thing happened but during the last couple hours of the fest, we encountered a chill group consisting of 3 girls. We danced with them (not on them) and right before the last set ended, I asked one of them for her snap and she gave it to me. She was friendly enough but was not giving me clear signs that she was interested. I also asked that night if she wanted to meet up on Sunday with us and she agreed that she wanted to.

So I guess one good sign was that she added me immediately on snap and responded to all of my messages. On Sunday, she and her group found us in the crowd because we had brought a pvc pipe with a flag on top. On that day, she was dancing in front of me but she never looked back at me or gave me any really solid eye contact. Keep in mind, this girl looks very young and I found out that all 3 of them are 18. During the last set on Sunday, she seemed talkative with her friend but didn’t really talk to me or turn around and dance with me. I feel like I should have made a move and danced on her considering she never really moved away from me but I didn’t want to be that guy. I snapped her today asking if she’d want to meet up for coffee or something like along the lines of that and she said yes. However, there is no concrete date set because she said she’s busy this summer. I was thinking maybe just waiting like a couple of weeks and asking again if she would be free to go out somewhere but I’d like your opinions first. I just think the lack of positives made me think she’s not interested, like her lack of eye contact and conversation with me. But her replying to me quickly, saying she wanted to see me and my friends the next festival day with her friends, and yes to a possible future coffee meetup makes me think maybe she’s just a bit shy. What should I do?

TLDR- inexperienced m21 having trouble reading if cute redhead girl is not interested in me or interested but just super shy
