This is an old story, it's been a long time it happened but at the time I was very concerned about what I did.
I noticed my best friends were avoiding me, and sometimes they were saying things behind my back, but I wasnt sure of what it was about.
And I happened to have the password to the skype account of one of them, and decided to spy on what they were saying about me in private.
I discovered a lot of conversations of them mocking me, and always trying to find ways to not be with me.
I was really shocked by that because they were good friend, and I didnt know what I did to desserve that.
I told them what I did because I felt bad about this (it was private conversations) and also I wanted to tell them we're not friends anymore.
It's been a few years, i've not talked to them since them (i never see them) but I still don't know if I was an asshole for doing that.
