Your lawyer may be able to go back to court to request reconsideration of the request for a restraining order in view of the new evidence. But you need to understand that Courts make decisions on these issues based on the evidence. Further, I am not so sure that the e-mails and text messages that you have are sufficient---they prove only that you knew the wife or your ex. However, unless they contain written threats to disclose embarrassing information, the e-mails and text messages may not help you. The time to go back to could would be if your ex-boyfriend's wife actually distributes embarrassing information about you---until then it will be hard to get a restraining order.
