Just wow, I can't tell you how much I relate to this.

My online friend has done exactly the same to me and it hurts like mad, I would make all the effort in the contacting, I had known her for 3 years, I had a long think about it and thought is this really worth getting upset about? So I sent her an email and told her how I felt and that I didn't want to be friends anymore.

She replied and started to get all angry with me as if it was my fault, I am no longer friends with her now.x
