We are both in our mid 20s. I don't really get where it started, maybe one time she was ticked by me giving a short reply, but I have always been a person giving a short reply.. Unless I needed to explain something.
I have tried multiple times inviting them for a voice chat/calls while we work on something, but she doesnt seem interested and I dont want to be the one that keeps knocking the invites. But it's one of the way we can communicate effectively since we rarely met in person and inability to read inflections over text might give it wrong meaning.
I'm also slightly annoyed that it's been the case but I am not even sure if I should confront it? In a first place I can't see myself being confrontational. This amount of petty fights isn't really important to begin with and not worth burning bridges over.
