So last week I approached a girl at the mall where she works. Im not really experienced yet, but it went really smooth. We grabbed a coffee the day after, while she was at work and she seemed really into me, gestures, talking, validations etc. She said she wanted to meet me again on the weekend for a walk, several times, wanted my facebook. She texted me as soon as I left. We texted one or two times the two days before the date, and lastly to set it up. She looked really intrigued. We were supposed to meet today, but last night I got a text from her (long one) saying she wanted to go out, have some fun, get to know me etc but she is not in the mood for new meetings/relationships. She doesn't expect me to understand, the problem is in her not me (lmao right) and shes really sorry.

I try to learn every single time from every experience, but this one really confused me. Opinions?
