Real story :

There's this one colleague, who was a very good friend of mine. Always helped me in everything. That one friend in the team, who shares a lot of stuff with you.

And she suddenly, turns offensive when it comes to professional things and mainly competitive stuff in the team.
She becomes a completely different person when I get recognition for something in the team or when I become popular in the team.

She has that feeling that she should always stay in the lime light.
When I steal the show by doing something good, she starts to show faces.
Decided that it is a unhealthy friendship, as the friend i knew is no longer a friend when it comes into professional behavior at work,
And it started reflecting a lot in our personal friendship, outside work too.

Decided to cut the friendship and only be colleagues.

Did the same happen to someone else? Did you lose a friend because of things like this?
