Suggestions on what I should do wth my friend?

Hey everyone, I am 17 and my best friend Natasha is 18. She had a baby about 1 year ago and we still hang out all the time. The problem is that her attitude these past few months has changed so much that I'm starting to constantly wonder how long we will last as friends. I have been good friends with her for about 5 years now. I know her family really well, and she knows mine the same. She acts very y though and always acts like everything is my fault when we get into a fight and calls me selfish. I am very sensitive and with her knowing that I don't know why she says some of the things that she has in the past ,but I feel that she can never admit when she's wrong. About a month ago she took some pictures of me at my friends pool and I asked her too take some of them down, The pictures were of me not of me and her, so I didn't see what the big deal was. Plus we all have pictures we don't like right? Anyways, She deleted me off her myspace and told me that I was being Dramatic, I sent her a message and apologized this is when she told me that everything was always about me, she's so forward about what she says sometimes. Everything is pretty much always about her, boyfriends that she can't get over and has to always talk about, her baby's daddy that doesnt see his daughter, her acciden't from 2 years ago and Just a lot of other stuff. I can probably give a lot better examples of a hurtful fight we have had but I dont wanna make this anymore longer. I guess I just dont like the way she talks to me. I'm her friend not her little sister. Should I talk to her about this and hope we don't get into a huge fight? Any suggestions on what to do about my situation would be very appreciated.
