So this is my problem: My best friend hassnt been talking to me and I asked her why she says its because I hurt her feelings I askd how and she said that it was my attitude she said that I had calld her once and I didnt care what she said and so I hurt her but here is the thing I called her because she hadn't said hi to me im like why didnt you say hi and blah blah blah I then told her that I didnt care and den I hangd up bt I was just playen I told her I was just p[layen I have witness that I was just playen bt she took it seriously and now she want talk da me or look at me she ignores me completly what do I do???

I don't know what to do because she has been acting in a manner that I don't know people say that if she b acting like she does with me then they don't know how she's my bff in the first place

Maybe something is going on somewhere else and she is taking it out on you
Make sure if everything is okay. Then talk things out. That usually always works.

Hey I went through something similar and it turned out my best friend liked me,but it might not be the case here but it could be she is really stressed and needs someone there for her cant think of much more to say hoped I helped.
