Is this how girls reject?

I've been texting with this girl for some time now, and asked her out for a movie last Thursday.

She laughed at first but agreed, so I was expecting much.

She used to text long and put lots of emoticons but then during the weekend she texts very late and so short answers such as "k. ya. bye"

Well so I asked her if she is free this weekend then she said she needed to go someplace,

so I asked when are you free about the watching movie, then she said "Sorry I couldn't go"

Is this how girls reject? It feels like I'd rather be rejected in the first place not after the appointment is set..
