Am I taking this the wrong way?

Ok, So like pretty much everybody I have a best friend.LOl. Ok, so she started hanging around this one girl. I noticed a change and how my friend has gotten like impatient and just rude to me. I think it was the other girl’s fault that she was hanging out with that made her this way. One day she went to the water-park w/ her, then the day after spent the WHOLE day w/ her. she came back and that’s when she started to act like that other girl! ok, so when she was gone the whole entire day w/ her and I called a bunch. I would have called less but I had no idea she was gone.The Whole day too . The next day which was Sunday, called me and asked if I was going to church w/ her. I like wasn’t even ready and it started in 20 min. I was like no, I tried calling you yesterday but you never called be back at all, if you called me I might be going w/ u. (I wasn’t yelling by the way) she was like srry and she said that at noon when it was over she was coming back and she’d hang out w/ me. 3 o click rolls by and she finally comes home! it was like 4:30 be4 she called me anyway. she was like oh sorry I was busy. She started to talk about that one girl and was like man she’s not going to be going to my school anymore. She’s going to a different one. MY so called best friend said: She’s my best friend and I’m not going to see her as much because she’s going to a different school!! She kept talking about her and stuff. I kept quiet and then she goes, Well, your my friend too it’s just I’ve known her longer. Oh, but she didn’t she actually knew me longer but no it didn’t matter to her!! I got off the phone and I was so upset I actually cried. It’s like imagine someone you love,like, or even your best friend telling you something similar to that?? Anyway, the next day she called me and wanted me to walk w/ her. So I decided that I was being foolish and acting immature. So we walk for like 5 min. and she starts talking about that one girl and stuff. She also starts complaining that’s it’s hot and she wants to tan. I couldn’t stand her nagging so I said if you want to go that bad then it’s fine go. She goes thankx In a half hour I’ll call you and we can walk more!! I go ok! So an hour rolls by and I call her. She answers and goes oops srry I 4got to call u, but now I’m going out to dinner w/ my family I’ll be back I’m two hours! SIX or SEVEN hours rolled by. After the 5th hour I gave up. So, now it’s 2day. I felt like telling her I feel like u’ve changed but I couldn’t. It felt like something was holing me back and stuff. She was telling me that she was going to be gone the whole day w/ her family and tommorow she’d hang out. I’m tired of waiting on her and I’m tired of how she’s acting. After all I wrote, am I taking this the wrong way. Who’s right me or her? should I talk to her? what should I say?? ANY advice for this heartbreaking situation would help.

Sorry, it’s soo long XOXO,
