I exposed my narc!

I exposed my narcissistic ex after being d&d for the second time, being ignored and a real long nasty call. I'm currently being given the silent treatment. During this time I've been cruel and down right nasty (yeah!). I sent him links on NPD and called him a psychopath... That he was unlovable and told him i was playing him.... I decided to take my pain and write a paper because I'm a psych major and sent him a bunch of examples of why he's a Narcissist and asked for feedback . He's not responded directly but made a post on twitter of not being scared and calling me a name.

However he did block me from his phone, he never did block me from Facebook where I sent my messages...

I don't get it. Why hasn't he iced me out all the way?

I'm in pain but I'm wanting to prevent a d&d three for fear I'll be weak... So I'm going hard and aggressive hoping he knows I'm done for real. I'm also wondering if it backfired because the negative attention could've given him the supply he needed...

Any similar stories of exposing and if it was truly the end?

Part of me ask for pleasure in ignoring him, the other in freedom if knowing I protected myself.
