Enough is enough. The eight years of "friendship" was a scam. Let's just accept that you're that kind of person and move on.
The point of the matter is, you have been making promises you can't keep, yet you can't have the decency to tell me about what's happening even through chat. I think I deserve to know, as a friend, and as I person, I deserve to know. You can't just walk in and out of other people's lives just like that.
That was the last chance. You blew it. Have a good life.
