Comment; is this girl crazy?

[Wren57]

One of my EXs, slowly but surely she is going insane... I was drunk and finally snapped.

Voicemail left by girl;
Someone is sending me and my roomate threatening messages and I better not find out it is you

Text message to girl;
I'm at a party was not me go away

Text message from girl;
Well you need to leave me and my roomate alone and stop sending us creepy messages

Text message to girl;
I didnt go away

Text message from girl;
Well if I find out you are in any way involved with those threatening messages I will report it

Call to girl;
Listen b!tch, I didnt send you any fvcking messages, Im at a fvcking party with my friends getting fvcking drunk, I dont give a sh!t about you or your fvcking roommate, I have no clue where the nearest fvcking computer even is, I dont want to have anything to do with you, I have a new girl and she is fvcking awesome so leave me the fvck alone b!tch *hangup*

Call back from girl- girlfriend picks up;
Stop calling my boyfriend *hangup*

Text message from girl;
Im not calling to talk to you, I got a threatening message and was asking about it. As for your gf, I hope she had fun hearing how you talk to your ex. It is sad that all your friends think its ok to talk to a girl like that.

Text message to girl;
But you are crazy so F off

The end.

Of course it wasn't me sending her the messages- I didn't even bother to ask the nature of the messages... don't really even care that she is being threatened... so am I completely out of line to think she is crazy?
