I need some advice on some friend help?

I have this friend. I took her to Quebec during my March Break, I thought it would be really fun having a good friend with me. We always o each other and would face time with our ipod touches. We were really excited for the trip. But I found that when we got there, for almost everything I said she would go against it. Like, when I told her that I heard somewhere that Justin Bieber get's his hair cut every two weeks for one thousand dollars. She then said: If that was true he wouldn't have anymore hair! And why would you believe something like that!" It's soooo annoying!!! And also, she always seems to try to seem as though her life is so much more stressful than mine. Once, we were putting our make up on and she says "I hate middle school! You always have to look so good!" I just ignored it though. And then one day we went shopping. And before we left she's like, "I hope your dad knows how much shopping means to us. We need hours!" And I said "we'll get around three hours, is that enough?" And she says no. I just kind of rolled my eyes. Later that day, after shopping, we left to go for dinner. And all through the time we were walking there she wouldn't say anything! She would just say "I don't know." or just not answer. That evening she appolapologized for being moody. She said it was cuz we didn't have much time for shopping. But I thought yeah, ok but you should be old enough to act proper when things don't go your way.

Then, one day, I was on the computer and she was beside me. She put her ipod touch on the table and I went to move my arm to put my hand on the track pad and I elbowed it off the table! The screen all shattered and I felt really bad because I didn't mean to do it. She said it wasn't my fault and it's under warrenty. Then when we left Quebec, and were back home, I bought her a gift to make up for it but she said not to worry about it and all. That was a week ago. We haven't texted since and when I went to text her a couple days ago, she would reply but (and I don't know how) I could feel that she wasn't giving much effort into the replys. Just a hey, whats up, nothing much responces. And now I feel like there's something wrong that she doesn't want to tell me. I need help so I know what I should do about her attitude
