Is she mad at me?

We are students at Uni. There's a shy girl we went on a date in Christmas eve very well, she told me although she likes me, so much, she thinks I am perfect in all ways, I don't seem to be serious enough to her and that turn her off. There's a guy she likes in her home country, but she is not sure if she wants to start a relationship with her, and that guy has texted her for 2 years without asking her for a relationship. And I told her I dont exactly like her, but she does has something quality to attract me and draw my attention. But we have continued texting each other, she replies so quick when she is free or even during midnight.

I brought up the topic about the transportation once. So she asked me to send her off to London airport (international student, going home for 2 weeks during holiday), but I told her I dont feel like spending more time and money on her. Last midnight before she went I brought up the topic again, she asked me again if I would go with her, I told her i will only go if she will buy me a return ticket. Meanwhile, she was worried how will she be able to manage her assignments after new years break, so I kind of teased her a bit saying something like "you are completely nothing and hopeless without me", and she said " thats why I need you.".

So after she has settled everything (buying tickets back home and preparing for assignments) She told me she does not need me to send her off anymore, she will no longer require my assistance. Before she goes this morning, I told her I really miss her in some way can I by chance go with her, she replied something like "no, just no".
