What do I do please answer?

OK, My one of my best friends I think is ignoering me. We havnt talked since this weekend. I try to text me but she doesnt reply but if she does its ALWAYS cant tlk. How i know thats a lie is when i text her other friend she says shes texting my best friend. Is she ignoreing me? If so what do I do? Where both 11 I am 4 days older then her. I dont know wat 2 do we never fite i didnt do anything, if i did though idk wat i did. I told my other best friend and they dont know each other but she had her num so she texted her y r u ignoreing Abby and so my friend that i thaugh was ignoreing me cussed her out but she still didnt txt me. So idk :(
