I Have No Clue What I Did Wrong

I seriously have no clue what I did to cause my friend to stop texting me. Its been two days since I've last talked to her and she seemed fine. Like I know I sent her 'as usual someone seems like they're not in talking mood' but she didn't seem mad about it. I said that because she kept giving me one text replies like she has always done and it was getting a bit annoying.

But again if its that, I don't think that should cause someone to stop texting a person. Even if she is mad about it, I'm trying to say sorry but she isn't replying at all to me. I texted a friend of her's that I know she would text and he told me that he and her were talking at the moment.

It must be something I did because its not her phone thats broken like I first thought. She's ignoring and I don't know why. I just texted her asking what did I do but again she didn't reply. So I asked her friend to ask her what I did. So now I'm waitng for a reply.

I don't know what it is about this summer. I'm losing like all my friends. Quite sad. Even my best friend barely texts me.
