I met this girl last week, we got along really well and there was a lot of playful flirting like touching and pretend fighting. She would often start conversations with me and come over to talk to me. She commented on both my Instagram and Facebook posts and flirting continued. We keep talking on snapchat and I asked her to the library on Sunday. In the library we continued to get on really well but the next day she worked somewhere else because she had a lot of work to do for a deadline due in a couple of days. But the next day she said she wasn’t sure if she would go to the library at all.

I’m not sure what’s happening, is she testing my interest? Or am I overthinking things? Should I ask her out to a more casual setting like coffee or should I accept that she’s not interested?
