I need some advice for working with someone who is no longer a friend.

I was sexually assaulted by a coworker in January. I tied myself into knots over whether or not to tell our mutual friend about it for over a month.

Initially, she was very supportive. Told me she believed me, she believed women, she called it rape when she confronted him and he admitted it over text message, said he was dead to her, etc.

Then I saw them chatting and laughing a few weeks ago.

I'm heartbroken, but my decision is very simple. There's no room in my life for someone who wants to be besties with my rapist.

Now, here's the fun part. I still have to work with her on a daily basis. I have to contribute to a positive work environment and not let my problem affect the rest of my crew.

I don't know how I'll be able to do this.
