It is difficult to tell from your question if the Order is an anti-harrassment or some other type of Order. I will answer the question assuming the Order is a temporary anti-harrassment Order and you are preparing for the hearing in which the Court can enter an Order effective for one (1) year or longer.
The anti-harassment statute requires two (2) elements be present in order for the judge to grant the requested Order. The alleged conduct must be considered harassment and second, the alleged conduct must be a continuing course of conduct, not an isolated incident. I suggest you prepare for the hearing with those two elements of the statute in mind.
I hate to tell you, but even if your version of events is true,a judge is likely to regard that conduct as sufficiently threatening to justify a protection order. If anything, given your intimate relationship, it is surprising that she did not petition for a domestic violence order. You should talk to a lawyer about your options.
Good advice by the other two attorneys. If you care about the result, I highly urge you to retain counsel to do this for you. Based on what you are saying, you are not going to win this, unless you have experienced trial counsel to perform a vigorous cross examination.
This answer is offered for informational purposes only. It is not offered as, and does not constitute, legal advice. Laws vary widely from state to state. You should rely only on the advice given to you during a personal consultation by a local attorney who is thoroughly familiar with state laws and the area of practice in which your concern lies.
