Wanting to scream

My worknarc pulled some stunt at work acting all casual and as if everything is fine between us and treating me like his other set of colleagues except hinting at very mild special attention to me.

I am so mad, I want to scream, cry, text him and tell him what I exactly think of him, to ask him to stop this drama and ask him to get lost and never come back.

Then I think this is exactly what he probably wants.

My charitable side wants to think: oh he is probably treating me like other colleagues and he is trying his best to act workplace normal and he is over the drama with me and this is the beginning of a peaceful coexistence.

My not so charitable side thinks: if he is going to be treating me well he would't give in mixed signals in all of 5 minutes.

I know that I have no control over any of this and I can change only how I react- how much longer for me in hell before I don't react? What else do I need to be doing other than LC/NC?
