Ignoring Friends


So some time ago I went to friend’s wedding and since then I havent heard from her and she didnt reply to any of my messages. Not sure the two are related, but it’s a bit weird.
C: Friend not replying to any of my messages.
T: I must have done/said something wrong…
F: Anxiety (I cannot really check the T on her side and on my view I did not do anything wrong)
A: I try to remember what might have triggered this; I “relaunch” her; I try to double guess, I am really acting a bit insecure, I am considering our common friends about the situation…
R: ??

And how I can help myself / situation?
