Another vote for calling the cops / bringing a law suit and restraining order. That kind of behaviour shouldn't be tolerated - and can get worse. Keep safe!

WTF? Your girlfriend is such a bitch. First of all, she wouldn't have had the right to do that even if you had cheated on her, and you could sue her for the damages even in that case. Second, your mom OBVIOUSLY didn't say anything that specified sleeping with you. There are lots of other ways to "have a good time" with a person that don't involve cheating. Even if she didn't recognize your mom's voice (which, contrary to popular opinion, I think is quite reasonable), she should have confronted/asked you about it in person before doing something so irreversible. Had she done that, you would have told her it was your mother, and she would have been embarrassed for having thought it was something so different, but no real harm would be done. You could laugh about it later, and have crazy make-up sex. :-p Given her current choice, though, you absolutely need to dump her. Make her pay for what she destroyed, and sue her if she refuses.

Holy crap. I hope you dumped her. What else will she destroy on a whim? Sounds dangerous.

kill her with fire! and anyone who put YDI should also be killed with fire.

I'd make her pay every cent, and then make her leave. She sounds dangerous.

Whoa. I hate when girlfriends start like freaking out. I mean really. Have some pride girls, don't just start running your mouth and breaking things. She's in deep shit now, I hope she pays for everything, even if she doesn't have a job she needs to get the money. On the other hand, why didn't you take her? I mean I can understand, maybe guys night out? At the same time I bet a guy somewhere in the world has cheated on his girl, and had the other girl leave a message, and said "oh no no no baby, that was my uhh.... mom!" Not saying the OP did that, but maybe the girl has some other relationship problems in the past? But by no means does it give her the right to destroy anyone's things. I hope everything turns out okay OP!

Get her to pay for what she destroyed. I would say you could even talk to the police, as what she did could be considered a crime. Threaten her with lawsuits and/or arrest if she doesn't pay up, and be true to your word. And naturally, dump her. She's a psycho.

Women... /sigh Tis that they can give us babies and they got boobs, but else.... the world could be a better place without em. (just kidding just kidding, stop throwing shoes at my face.)

Dump your crazy girlfriend after you make her pay for your shit!

Destruction of Property...I'd find a good attorney, and then drop her ass.
