What happens when you break your own restraining order?

Our neighbors constantly fight and scream and break things.. A while ago she moved out.. HE then started buying a lot of stuff (Playstation 3, HUGE big screen tv.. expansive stuff) On THanksgiving, we noticed she was over here and they kept screaming and sounded like stuff was being thrown.. My bf went down there and asked if they needed us to call the cops (they've been called before by other people and they've been in trouble for domestic disturbance).. they said no, and the guy was complaining she just broke his brand new tv.. was completely drunk.. and not supposed to be there.. Later she left, completely tanked.. The police came the other day looking for him, but he wasn't home.. Turns out he filed charges against her for breaking his tv, and she turns around and files a restraining order on him... so they were looking for him to get him the paperwork. BUT last couple of nights, she's been back here. We haven't heard screaming or anything, but she's off the lease, not supposed to be here, and supposedly has a restraining order against him. What happens when you break your own restraining order, if anything??
